The disclosed systems, methods, and structures are directed to LoS MIMO communications that optimize spectral efficiency and include a precoding module to multiply an input transmit data vector with a precoding matrix to generate a precoded transmit data vector, a gain matrix calculation module to generate a gain matrix having optimal gain values that maximize the spectral efficiency, a transmit signal processing unit to convert the precoded transmit data vector into an analog signal, a receive signal processing unit to receive the analog signal and convert the analog signal into a receive data vector, an equalization module, a channel estimation module to estimate channel information to generate an estimated channel, and a singular value decomposition module to decompose the estimated channel matrix. The gain matrix calculation module calculates the optimal gain values of the gain matrix by maximizing an objective function encompassing the channel information provided by a fed-back diagonal matrix.
