Patent ID: 7929643

Claim:
A method for receiving symbols of a sequence transmitted on at least two transmission channels through AM-PSK modulated signals, a sequence of known symbols being established and transmitted for the sequence of symbols for estimating the fading coefficients of the transmission channels, the method comprising: in each symbol period, receiving a linear combination signal as a combination of the AM-PSK modulated signals; extracting a first DC component from the received linear combination signal via a coherent demodulation locked to a first phase; extracting at least a second DC component from the received linear combination signal via a coherent demodulation locked to a second phase; generating first estimations of each transmitted symbol based upon the estimated fading coefficients, the DC components and mutual outphasing between the AM-PSK modulated signals; estimating unknown phases corresponding to the transmitted symbols based upon the respective first estimations; estimating further fading coefficients of the channels based upon the first estimations, the DC components, the mutual outphasing between the AM-PSK modulated signals and estimations of previously transmitted symbols; at the end of a symbol period, determining the values of transmitted symbols based upon the respective estimated phases in the symbol period.
