摘要： The present invention addresses the problem of a second (or higher) order representation of a transmit signal which is transmitted by a transceiver being mixed into the region of the frequency spectrum of interest to the transceiver receiver, such that it can not then be spectrally filtered out. At its most straightforward, in one embodiment of the invention this is achieved by providing a cross-talk cancellation unit which takes the transmit signal, and obtains the second (or higher) order representation thereof. This representation is then subtracted from the received signal before the signal is passed to the radio control receiver signal processing elements. However, in a more preferred arrangement a filter is also provided, to filter the second or higher order version of the transmit signal, prior to its being subtracted from the received signal. The filter basically takes out the effects of any other filtering or processing which has happened to the transmit signal in the receiver signal chain. This would be, for example, the filtering effects provided by the anti-aliasing filter in the receiver.

摘要： A method of estimating a pitch period of a first portion of a signal wherein the first portion overlaps a previous portion. The method comprises computing a first autocorrelation value for part of the first portion not overlapping the previous portion. The method further comprises retrieving a stored second autocorrelation value for part of the first portion overlapping the previous portion, the second autocorrelation value having been computed during estimation of a pitch period of the previous portion. The method further comprises forming a combined autocorrelation value using the first and second autocorrelation values, and selecting the estimated pitch period in dependence on the combined autocorrelation value.

摘要： A method and apparatus for decoding portions of a data stream, wherein each portion comprises a plurality of samples. The method comprises storing portions of the data stream, decoding portions of the data stream to form decoded portions, and storing the decoded portions. The method further comprises identifying that a portion of the data stream is degraded. Following identifying that a portion of the data stream is degraded, the method generates a decoded portion for the degraded portion of the data stream using the stored decoded portions. The method also updates a state of a decoder by: estimating a pitch period of the degraded portion; selecting a group of successive samples of the stored portions of the data stream, the group of successive samples offset from the degraded portion in the data stream by a multiple of the estimated pitch period; and decoding the selected samples at the decoder.
