Method for sending a signal in a multi-antenna system, corresponding signal and method for channel estimation

摘要

The method involves associating vectors to be transmitted by four transmitting antennas (11-14), to a source data vector, with the help of coding matrix whose output is equal to one. Two transmission channels corresponding to the antennas are estimated using a receiver. Reference symbols are subjected to mathematical transmission by the coding matrix before their transmission. Independent claims are also included for the following: (A) a digital signal (B) a method of estimating a transmission channel in a multi-antenna system.
