Abstract
The achievable rate of the multi-input multi-output (MIMO) channel with low-resolution receiver ADCs is analyzed. With the channel state information at both the transmitter and receiver, we jointly optimize the transmit signal and the receiving analog combiner with an aim to improve the performance. To this goal, the approximate achievable rate of considered channel model is first obtained using the Bussgang theorem. After that, the singular-value decomposition (SVD) based approach is proposed to enable the joint optimization. Our simulation results show that the proposed design is able to reach the capacity at low signal-to-noise ratio (SNR).
