摘要：
PROBLEM TO BE SOLVED: To perform synchronization and equalization without using a training sequence in mobile communication. SOLUTION: A method and system performs blind joint channel estimation and signal detection in a communication system that includes multiple channels for transmitting symbols. The multiple channels are estimated using a small number of symbols initially received through the multiple channels. When the channels have been estimated, a single best channel is selected. From then on, the bulk of the symbols are detected only on the best channel, while the best channel is updated. COPYRIGHT: (C)2004,JPO
