of the devices is maa featured such as the pair 11 13 in fig1 and will be a 2 dimensional matrix when both communication devices are maa featured such as 12 and 13 in fig1 in an indoor or urban wireless network deployment due to the scattering nature of the propagation channel the elements of the matrices h will typically but not necessarily be weakly mutually correlated random variables provided that the multi antenna array elements are properly spaced and designed in a typical deployment of the proposed invention the channel matrix 15 will be quasi static and will only vary negligibly since the time the h estimates or the information derived thereof are made available at both right and left sides just prior to transmission start and till the end of the transmission burst period due to the channel 15 signal attenuation and interference properties to inherent physical limitations of the receiving side components to practical limitations in channel training stage duration and to practical or regulatory limitations in transmission power the estimate of channel 15 will be usually noisy and will be thus denoted by hn to distinguish it from the fore mentioned actual channel matrix h it will also generally be assumed along this invention description that immediately prior to said channel acquisition the processes of carrier frequency and symbol timing information estimation and extraction have been completed so that both carrier frequency and symbol timing are known down to reasonable accuracy.
