Abstract  Abstract

PROBLEM TO BE SOLVED: To maximize diversity for data transmission over as many dimensions as possible for obtaining strong characteristics.

SOLUTION: For transmission diversity in a multi-antenna OFDM system a transmitter encodes interleaves and symbol maps traffic data to obtain data symbols. The transmitter processes each pair of data symbols to obtain two pairs of transmission symbols for transmission from a pair of antennas either (1) in two OFDM symbol periods for space-time transmission diversity or (2) on two subbands for space-frequency transmission diversity. N T(NT-1)/2 different antenna pairs are used for data transmission along with different antenna pairs being used for adjacent subbands where NT is the number of antennas. The system may support multiple OFDM symbol sizes.
