Patent ID: 7369487

Claim:
A receiver comprising: a plurality of branches i, where index i=1, 2, . . . m, each including an FFT element FFT i responsive to respective a receiving antenna, FFT i developing signals y[i,n,k], where n designates time, and k designates a tone, and further included a filter F i responsive to FFT i , where F i employs coefficients Ĥ*[i,n,k]; a combiner responsive to output signals of said filters; a threshold decision element responsive to output signal of said combiner; and a channels estimator, responsive to output signal of said threshold decision element and to signals y[i,n,k] of all of said FFT elements, for developing, for each index i, said coefficients Ĥ*[i,n,k] and applying said coefficients to said filter F i .
