摘要： A novel and useful apparatus for and method of determining the channel order and channel estimate in a communications system such as a wireless communication system including cellular and cordless. Such channels are typically characterized by rapidly changing impulse response and their taps can be modeled as zero-mean, complex, Gaussian random processes. A sufficiently long, initial channel estimate of length is performed so as to ensure that the actual channel taps will be contained in the estimated taps thus making certain that the equalizer will effectively eliminate intersymbol interference. Channel estimation is performed during each burst using the training sequence transmitted in the middle of the burst. The tap energies are averaged so as to track slow variations in the pattern of resultant channel taps. A noise floor is calculated using the lowest averaged taps and a threshold is computed based thereon and applied to the average taps. The channel order and the tap positions are then selected in accordance those average taps that are above the threshold.

摘要： The present invention discloses a novel scheme of performing frequency domain filtering that does not require a Hilbert transform and which is faster than equivalent FIR filtering schemes. Such a scheme has applications in implementing filters in voice band modems on OSP platforms and in numerous other applications as well. The scheme of the present invention is shown to be superior in term of CPU resource consumption and memory storage space when compared with an equivalent implementation using prior art time domain convolution techniques. The scheme of the present invention permits the delay buffer in the far end echo canceler to store the signal in real format rather than complex format, thus reducing memory requirements by half. The present invention implements a real to analytic fast convolution in the frequency domain which uses zero CPU resources.

摘要： An apparatus for and method of implementing a novel buffer based fall duplex communication system is disclosed. The disclosed invention is particularly useful in native signal processing systems wherein heavy contention of processor resources typically exist, such as in systems running multi-tasking operating systems. The communication system of the present invention includes a receiver, transmitter, CODEC and telephone hybrid. The major components of the system operate on a buffer of input samples consisting of a set of input bits. The communication system operates to generate a buffer of output samples consisting of a set of output bits. The invention utilizes a novel dynamic buffer size mechanism to optimize the tradeoff between buffer delay and processing time period, on one hand, and robustness to interrupt latency and processor availability on the other hand. Small buffers provide the communication system with short, accurate response times in addition to short processing times. Using a large buffer of spare or dummy samples to be transmitted while the CPU is unavailable reduces the probability of a buffer underrun, thus giving the operating system greater leeway in deciding the exact time the signal processing functions in the modem routine are run. In this manner latency time is held to a minimum and data is not lost or corrupted. The concept of using dummy bits or silence for the generation of spare samples enables the elimination of additional latency caused by the spare samples by overriding them if they are not transmitted. This is achieved without a loss of signal coherency.

摘要： An apparatus for and method of implementing a novel buffer ba full duplex communication system is disclosed. The disclosed invention is particularly useful in native sign processing systems wherein heavy contention of processor resources typically exist, such as in systems running multi-tasking operating systems. The communication system of the present invention includes a receiver, transmitter, echo canceler. CODEC and telephone hybrid. The major components of the system operate on a buffer of input samples consisting of a set of input bits. The communications system operates to generate a buffer of output samples consisting of a set of output bits. The invention utilizes a novel buffer switching mechanism to optimize the tradeoff between processing response time, on one hand, and robustness to interrupt latency and processor implementation on the other hand. The internal processing of the modem works on a buffer full of samples once every time slice thus reducing the probability of a buffer underrun/overrun error occurring. The reduction in probability of data underrun/overrun is achieved by increasing the buffer size, thus giving the operating system greater leeway in choosing the exact time the signal processing functions are run. Small buffers, however, provide the communication system with short and accurate response time. These contradicting motives lead to the novel switchable size buffer scheme of the present invention. This is achieved without a loss of signal coherency.

摘要： A novel system by which the utilization of a central processing unit (CPU) in performing filtering operations can be reduced by shortening the filter's length thus degrading the performance of the system down to a predetermined level or threshold. The present invention is applicable to such systems that incorporate filters whereby shortening their length decreases the performance of the system and to such systems where a reliable quality criteria exists that can be measured during run time. A method iteratively minimizes the filter's length so that the quality criteria does not fall below a predetemined threshold level. In addition, a signal to noise ratio (SN) criteria is suggested for estimating the quality of the reception of communication signals. An implementation is suggested for the method in the particular case of an echo cancellation adaptive filter. In addition, a method for determining an immediate approximation of the echo canceler filter's length as opposed to finding it iteratively.
