摘要： The embodiments of the present invention relate to a method in a transmitting unit; a method in a receiving unit; a transmitting unit and a receiving unit, in a wireless communication network employing Time Division Multiple Access, TDMA, for transmitting and, receiving and demodulating data, respectively, the data being transmitted in a signal comprising a burst, wherein bursts relating to NMS number of mobile stations are multiplexed into a single time slot. The transmission comprises grouping a block of N b number of user code bits, representing the data to be transmitted, into NDS/NMS groups of user code bits. Mapping the groups of user code bits to data symbols such that one group is represented by one data symbol, thereby obtaining a block of data symbols, wherein each data symbol is drawn from one or more pre-defined complex-valued symbol constellation(s). The transmission further comprises repeating the block of data symbols, such that the burst to be transmitted comprises NMS number of equal blocks of data symbols, rotating the NMS number of blocks of data symbols according to a mobile-station-specific rotation, and transmitting the rotated blocks of data symbols in a burst in the time slot.

摘要： A modulator includes a symbol mapper that is configured to map respective bits sets of a bit sequence corresponding to a burst and including data, training, tail, and guard bits into respective symbols to form a symbol sequence of data, training, tail, and guard symbols. A vector precoder is configured to apply a vector precoding transformation to the data and training symbols to form precoded symbols. These precoded symbols are combined with the tail and guard symbols in a symbol processor to form a sequence of transmit symbols. The record precoding conducted by the modulator of a transmitter enables improved link performance without the cost of increased processing complexity of the receiver algorithm.
