摘要： 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. The available frequency bands are divided into at least two sub-bands, with frequency translations ocurring entirely within a given sub-band.

摘要： 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.

On the transmit side, a transmit section contains a plurality of digital signal processors, respectively associated with respective ones of a plurality of incoming (voice/data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.

摘要： 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.

摘要： 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.
摘要翻译：无线通信系统包括多个宽带基站和动态地控制基站之间的信道分配的群集控制器。当基站不能在其小区站点内服务无线电话终端时，基站轮询信道并向控制器发送对信道的请求，在请求中列出站点在小区站点确定为非活动的信道。控制器将查询负载统计信息表，以确定系统中首个列出的通道是否可用。如果是这样，则控制器将该信道分配给基站，如果控制器在表中没有搜索空闲信道则分配该信道。控制器还可以包括表中的信道使用率。这些速率指示每个基站的预定时间段，基站向终端分配信道的速率和同时使用的信道数量。控制器检查与分配空闲信道的基站相关联的信道使用率，以确定该速率是否低于预定的最大值。如果是这样，控制器分配通道。否则，控制器在表中搜索下一个免费列出的频道，等等。控制器还可以基于预期的使用将信道预分配给基站。为了确定预期的使用，控制器在多个预定时间段内累积通道使用信息，并且如果可能的话确定使用模式。然后，控制器在适当的时间，即当模式指示使用的改变时，以低预期的使用方式从基站预先分配具有高预期用途的基站的信道。
