Abstract:
1. A method of transmitting data using a space-time block code in a wireless communications system comprising a source node, a relay node and a destination node, the method comprising: the source node transmitting RF signals representing first and second sets of data symbols in respective first and second channels of the wireless communications system, the first and second sets of data symbols being for transmission from separate antennas respectively according to the space-time block code, wherein the data symbols in the second set of data symbols are functions of the data symbols in the first set of data symbols; the relay node receiving the RF signals representing the first set of data symbols in the first channel, selecting the first set of data symbols from the received RF signals and transmitting RF signals representing the first set of data symbols in the second channel; and the destination node receiving the RF signals representing the second set of data symbols from the source node and the RF signals representing the first set of data symbols from the relay node, thereby enabling decoding of the received RF signals representing the first and second sets of data symbols according to the space-time block code.
