Abstract: A transmitter comprises a block generator (109) which divides a data symbol stream into data symbol blocks. A divide processor (111) divides each block into a first set of data symbols stored in a first set buffer (113) and a second set of data symbols stored in a second set buffer (115). A space time block encoder (117) codes the first set in accordance with a space time block code to generate a coded set of data symbols. A parallel processor (119) then creates a plurality of parallel data streams from the coded set and the second set. Each of the parallel data streams is allocated to one of a plurality of antennas (129-135). A plurality of parallel stream transmitters (121-127) transmits the parallel data streams in parallel in a communication channel from the plurality of transmit antennas (129-135).

Abstract: An Orthogonal Frequency Division Multiplex (OFDM) transmitter (100) comprises a symbol generator (103) for generating a first OFDM symbol comprising user data and pilot data where the pilot data comprises a set of predetermined non-orthogonal pilot symbols. A weight generator (109) uses an amplitude estimator (107) for selecting a set of weights for the pilot data of the first OFDM symbol in response to a time domain amplitude variation characteristic of the first OFDM symbol. In particular, the peak to average power ratio may be determined. The set of weights are selected from a discrete alphabet of weights. A weight processor (113) determines a second OFDM symbol by weighting the pilot symbols by the set of weights. The second OFDM symbol is transmitted to a receiver without transmitting identification of the selected set of weights. The receiver may perform a blind detection of the applied weights and may compensate the received pilot symbols for the estimated weight.
