摘要
Relay nodes relay data from a source node (110) to a destination node (130) in an asynchronous cooperative wireless communication system. Each relay node (120) includes a serial-to-parallel partitioner (212), a row selector (214), a cyclic shifter (216) and an SCBT modulator (218). The serial-to-parallel partitioner partitions symbols corresponding to received information into parallel blocks. The row selector selects one row of a coding matrix for each of the parallel blocks and constructs symbol blocks corresponding to the parallel blocks based on the selected row. The cyclic shifter shifts a cyclic delay of each of the symbol blocks and generates shifted symbol blocks corresponding to the symbol blocks. The SCBT modulator pads a guard interval to each shifted symbol block to remove the effects of asynchronous relay transmission. Constructing the symbol blocks and generating the shifted symbol blocks provides virtual spatial diversity among the relay nodes, which varies directly with a number of participating relay nodes.
