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.

摘要： Compressive sampling is used to generate pilot symbols to be transmitted over an array of antennas in a MIMO wireless communications device. A pilot symbol is transmitted over the array of antennas according to a spatially randomized antenna transmission function that randomly changes across the array of antennas. The randomized antenna transmission function may randomly select/deselect antennas and/or randomly change amplitude and/or phase of the pilot symbol transmission. Channel estimates can be constructed at a receiver based on the spatially randomized pilot symbols that were transmitted.

摘要： Multi-antenna transmission control presented herein involves generating a set of virtual channel realizations at the transmitter that shares the same second-order statistics as the actual channel realizations observed for a targeted receiver. By making the control-related quantities of interest at the transmitter depend on the long-term statistics of the channel, the actual channel realizations are not needed for transmission control, e.g., for accurate Multiple-Input-Multiple-Output (MIMO) preceding. As such, the use of virtual channel realizations enables transmission control that approaches the “closed-loop” channel capacity that would be provided by full feedback of the (instantaneous) actual channel realizations, without requiring the overhead signaling burden that attends full feedback.
摘要翻译：本文提出的多天线传输控制涉及在发射机处生成一组虚拟信道实现，其共享与针对目标接收机观察到的实际信道实现相同的二阶统计。通过使发射机处的控制相关数量取决于信道的长期统计，例如对于精确的多输入多输出（MIMO）预编码，传输控制不需要实际的信道实现。因此，虚拟信道实现的使用使得接近将通过（瞬时）实际信道实现的完全反馈提供的“闭环”信道容量的传输控制，而不需要出现完全反馈的开销信令负担。
