摘要：
A method and apparatus for determining a shuffling pattern in a DSTTD. In the apparatus, a channel estimator estimates channel characteristics from a plurality of transmit antennas to a plurality of receive antennas. A shuffling pattern selector calculates a minimum receive SNR for each of all available shuffling patterns, and selects a shuffling pattern having the largest minimum receive SNR as the optimum shuffling pattern. This efficient shuffling pattern selection directly improves BER performance at a receiver.
