A CODING METHOD OF SPACE-TIME TRELLIS CODES

摘要

The present invention provides a space-time trellis coded method comprising: at transmitting terminal: inputing signal bits are encoded using a space-time trellis code; modulating the coded data; sending modulated signals upon transmitting antenna to the communication channel; at receiving terminal: receiving antennas receive the signals upon the communication channel from said transimitting terminal; characterised: said space-time trellis code has symmetric structure, in searching said space-time trellis code must accord with symmetric configuration condition, said space-time trellis code having symmetric configuration is the best among all the corresponding space-time trellis code. Said space-time trellis code can attain the completely diversity gain and the maximal coding gain simultaneous.
