SVD-Assisted Joint Precoder and Decoder Design for the Uplink of MU-MIMO Systems With Improper Modulation
This paper considers noniterative joint precoder and decoder design for uplink multi-user multiple-input, multiple-output systems, for both cases of perfect channel state information (CSI) and imperfect CSI at the transmitter and receiver. Instead of counting on complex iterative based algorithms, an efficient and noniterative SVD-based joint precoder and decoder pair design is employed. It also focusing on the scenario when an improper constellation such as binary phase shift-keying or \(M\)-ary amplitude shift-keying (\(M\)-ASK) is employed. The proposed are novel joint linear precoders and decoders design aims to minimize the total mean squared error of the symbol estimation. Simulations are conducted to provide a comparative evaluation of the proposed design over the previous designs on the bit-error-rate performance.
