Abstract: A wireless system architecture whereby high efficiency broadband transceiver systems can be deployed at an initial build out stage of the system in a cost-efficient manner. A home base station location is identified within each cluster of cells and rather than deploy a complete suite of base station equipment at each of the cells in the cluster, inexpensive translator units are located in the outlying cells serviced by the home base station in which low traffic density is expected. The translators are connected to directional antennas arranged to point back to the home base station site. The translators are deployed in such a way which meshes with the eventually intended frequency reuse for the entire cluster of cells. The translator to base station radio links operate in-band, that is, within the frequencies assigned to the service provider. For example, the available frequency bands are divided into at least two sub-bands, with a first sub-band is assigned for use as a home base station to translator base station communication link and a second sub band is assigned for use by the mobile station to translator communication link. If desired, a third sub-band can then be used for deployment of base transceiver systems in the conventional fashion where the base station equipment located at the center of a cell site communicates only with mobile stations located within that cell.

Abstract: A distortion correction technique for use with a high power amplifier (HPA) in a multi-carrier radio signaling system such as a cellular base station. Distortion correction is implemented by making use of a broadband digital composite signal input to the high power amplifier as a reference signal in a form of intermediate frequency (IF) distortion correction circuit. A multichannel synthesizer provides the broadband composite signal to a broadband digital radio which in turn provides an input to the (HPA). A portion of the output signal from the HPA is fed back through a radio frequency (RF) and intermediate frequency (IF) down-conversion stage that uses the same IF and RF local oscillators that were used to generate the input signal to the HPA. This feedback signal is fed to a predistortion processor together with a version of the composite digital signal. The predistortion processor may perform a first crude amplitude correction procedure by finding a difference between the HPA feedback signal and the composite signal, to provide an offset to be loaded into a look-up table which is disposed between the broadband digital synthesizer and the broadband digital radio,. Subsequent precise correction and distortion correction procedures are performed using the offset value.

Abstract: A technique which enables the use of a low cost linear power amplifier to generate a wideband composite signal, such as in cellular mobile telephone (CMT), personal communication system (PCS), or other multi-channel wireless systems. A composite signal is generated by a wideband digital combiner as a frequency multiplexed combination of many narrowband modulated digital carrier signals. The technique involves introducing predetermined phase shifts into each of the digital channel signals after a baseband modulation step. The wideband composite signal thus exhibits a reduced peak-to-average signal power, despite the fact that the phases of the digital carrier signals cannot be directly controlled. This permits the use of a power amplifier, which may have a much smaller peak-to-average rating.

Abstract: A wireless communication system includes a plurality of wideband base stations and a cluster controller that dynamically controls channel allocations among the base stations. When a base station can not service a radio telephone terminal within its cell site, the base station polls the channels and sends a request for a channel to the controller, listing in the request the channels the station determines at the cell site to be inactive. The controller consults a load statistics table to determine if a first listed channel is free over the system. If so, the controller allocates the channel to the base station, if not the controller searches the table for a free channel. The controller may also include channel usage rates in the table. These rates indicate for a predetermined period of time for each base station the rate at which the base station assigns channels to the terminals and the number of channel in use simultaneously. The controller checks the channel usage rate associated with the base station to which the free channel is allocated to determine if the rate is below a predetermined maximum value. If so, the controller allocates the channel. Otherwise, the controller searches the table for a next free listed channel, and so forth. The controller may also preallocate channels to the base station based on expected use. To determine expected use, the controller accumulates the channel usage information over a number of predetermined periods of time and determines a pattern of use, if possible. The controller then, at appropriate times, i.e., when the pattern indicate changes in usage, preallocates channels from the base stations with low expected use to the base stations with high expected use.
