摘要： An access probe existing and generated within a base station to simulate a mobile terminal for the purpose of testing base station receive functionality within a communications system. The access probe data is injected at baseband rather than at RF to eliminate the need for analog/RF circuitry. The access probe performs injection at the front end of the base station receiver to exercise as much receive data path as possible. A unique ID is embedded in the access probes so that the communications system is aware which probes within a sequence were received successfully and at what power level. Within in-field applications, the unique ID allows the communications system to distinguish simulated access probes from those corresponding to real mobiles.

摘要： Methods and apparatus for performing finger de-spreading and MRC combining are provided. A large antenna buffer is used to buffer all the finger signals of the same user so that the receiver can do both de-spreading and MRC at the same time without buffering the de-spreading finger symbols. For each user, a reference time is introduced to align all the finger signals of the same user in the Antenna Buffer. The reference time delay is used to generate the PN codes for de-spreading, as well as to count the number of symbols in a PCG or a frame. Methods for antenna buffer arrangement, interpolating filter implementation, channel estimation and MRC for traffic data channels, timing for the user's finger signal de-spreading and MRC, long code and short code generation for de-spreading, new finger allocation and finger timing adjustment.

摘要： A method and apparatus for compression of complex data signals within a telecommunications base station. The method includes representing a sample of a complex value discrete time signal using 2(L−N)−S mantissa bits and 2N+S exponent bits to realize peak output signal to noise ratios over a wider dynamic range compared to a conventional L-bit uniform quantization format. The increases in dynamic range and peak output SNR is achieved without increasing the average number of data bits per sample and with relatively simple computational effort.
