Receiver structures for spatial spreading with space-time or space-frequency transmit diversity

Space - receiver entity 150 for data transmission having at least one data symbol stream is transmitted using a time transmit diversity (STTD) to obtain the received symbols. The receiving entity derives a total channel response matrix in accordance with the STTD encoding scheme used for the transmission data, based on the overall channel response matrix, derive the spatial filter, and space for a vector of received symbols from each of the 2-symbol interval by performing the matched filter to obtain a vector of detected symbols for the 2-symbol interval. After receiving entity for the detected symbols, if necessary, - the processing can be performed (e. G., Conjugated). Alternatively, the receiving entity derives a spatial filter matrix based on the effective channel response matrix, and performs spatial matched filtering on the received symbols for each symbol period to obtain detected symbols for that symbol period . The receiving entity space - to obtain received symbols for a data transmission having at least one data symbol stream transmitted using the time transmit diversity (STTD). The receiving entity derives a total channel response matrix in accordance with the STTD encoding scheme used for the data transmission, based on the overall channel response matrix to derive the spatial filter matrix, a vector of received symbols for each 2-symbol interval It performs spatial matched filtering to obtain a vector of detected symbols for the 2-symbol interval. After receiving entity for the detected symbols, if necessary - it performs the processing (e. G., Conjugated). Alternatively, the receiving entity derives a spatial filter matrix based on the effective channel response matrix, and performs spatial matched filtering on the received symbols for each symbol period obtain detected symbols for that symbol period and using the STTD combines a number of estimates obtained for each transmitted data symbol.
