Abstract: A receiver decodes quantized and unquantized wanted data symbols from received signal samples. The receiver comprises a control adapted to process a group of currently received signal samples to determine a corresponding current set of unquantized wanted data symbols and an interfering waveform representative of a sum of other unwanted data symbols by subtracting an amount of a previously decoded set of quantized wanted symbols and a previously determined interfering waveform. A quantizer quantizes the determined current set of unquantized wanted symbols to obtain corresponding quantized symbols.

Abstract: A vector tree correlator correlates over received data spread at differing spreading rates or, over differing lengths of spreading sequence. When the maximum length sequence has a length N that is an integer power of 2, or 2M, then the vector tree correlator is formed from M levels. Level (1) is formed of add/subtract logic units, and Level (2) through Level (M) are formed of adders. Add/subtract logic units each receive a pair of received signal samples and combines the received signal samples based on a control signal input. The control signal input is derived from the locally generated spreading sequence. The output of the adder at the top of the tree is the result of the length N correlation, while output tap points at different levels of the tree each provide a correlation for one of the different spreading rates of length 2m, 1

Abstract: A subscriber unit for controlling transmission power during the establishment of a communication channel utilizes the transmission of a short code during initial power ramp-up. The short code is a sequence which has a much shorter period than a conventional access code. The ramp-up starts from an initial power level which is quickly increased, while repeatedly transmitting the short code until a detection signal is received by the base station. The use of short codes limits power overshoot and interference.

Abstract: In an information transmission method, a radio communications system, a base station and a mobile station, a TBS size, a modulation scheme and the number of codes in a multicode are converted into identification data having a relatively smaller data size before being transmitted to a destination of communication. The TBS size is identified by using, in combination, an identification code identifying a channelization code set, an identification code identifying a modulation scheme, and an identification code obtained by converting a combination of the number of codes in a multicode and a modulation pattern identification (TFRC) into a corresponding code. Accordingly, the data size for TBS size identification is reduced.

Abstract: A subscriber unit, used for communicating in voiced communications at a first data rate and communicating at a second data rate for other data, suppresses a selected communication during communication rate modification. A determination is made as to whether the transmission requires a change in data rate, and a switching circuit responds by engaging a different communication channel. Blocking circuitry blocks transmissions until the different data rate is established. This provides an optimum data rate, while preserving the integrity of the data transmitted.

Abstract: A method and system for canceling interference in a code division multiple access (CDMA) network. A transmitted signal is spread using a specific spreading sequence. The signal includes a plurality of symbols having a specific spreading factor that differs from the length of the spreading sequence. The transmitted signal is received and filtered using a plurality of despreading sequences to recover the transmitted signal, wherein each despreading sequence corresponds to a particular part of the spreading sequence and is used to despread a portion of the received signal that was spread using the corresponding part of the spreading sequence. Each despreading sequence is adapted to cancel interference caused by other signals, wherein such interference is associated with the part of the spreading sequence that corresponds to the despreading sequence.
