Abstract

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.

Description

technical field

[0001] The present invention mainly relates to a dual space-time transmission diversity (DSTTD) system, in particular to a method and a device for selecting a shuffling mode in the DSTTD system for shuffling and transmitting data streams. Background technique

[0002] With the rapid growth of the wireless communication market and the increasing demands of various multimedia services in the wireless environment, various methods of transmitting large amounts of data at a relatively high rate are constantly being explored and studied. Therefore, the full use of limited frequency resources has become a top priority. A new transmission scheme using multi-antenna technology came into being. The standardization working group of 3G mobile communication system, 3GPP (3rdGeneration Partnership Project) is actively using MIMO (Multiple Input and Multiple Output) technology, that is, in the mobile communication environment through Set up multiple transmit / receive antenn...
