摘要：Space time coding (STC) may be applied at the transmitter adding redundantinformation in both space and time dimensions. At the receiver, the received STC signalmay be decoded using a spatial multiplexing MIMO decoding, for example, based oneither Minimum Mean Square Error (MMSE) or maximum-likelihood (ML) algorithms. Aselective STC decoder may incorporate both the conventional maximum ratio combining(MRC) decoding scheme and a MIMO decoding scheme. One of the STC decodingschemes may be selected, for example, based on estimated channel conditions in orderto achieve a trade-off between error rate performance and computational complexity.Components used for a non-selected scheme may be powered down.
