The present invention provides a method and system for receiving a plurality of information signals at a receiver. The information signals each traveling through a corresponding transmission channel. The receiver includes a plurality of receiver channels, wherein each receiver channel receives a corresponding information signal. An amplitude of each received information signal associated with each receiver channel is adjusted so the amplitudes of all the received information signals are as great as possible, while still maintaining a target level of signal error of each of the received information signals. The amplitudes of the received information signals can be additionally adjusted so that the signal errors of each of the received information signals are approximately equal. Each receiver channel can be calibrated by measuring a noise reference and a distortion reference for aiding in the estimation of the received information bit stream. The received information signals can be multiple carrier signals, and calibrating each receiver channel can be accomplished by receiving the multiple carrier signals in which at least one sub-carrier of the received multiple carrier signals is nulled, and the noise reference and the distortion reference of each receiver channel are estimated during the reception of the nulled sub-carrier. The receiver can include spatial processing and demodulation that provides estimation of the received information bit stream for spatially multiplexed or transmit diversity received information signals. |
