  Abstract

In recent years, massive MIMO has attracted a great attention as one of key technologies for 5G communication systems. In frequency division duplex (FDD) massive MIMO systems, the large-scales antennas make channel feedback overhead very heavy. Thus, the efficient limited feedback method and codebook design are required to circumvent this difficulty. In this paper, we propose channel-correlation-based two-stage quantization and codebook design for the efficient quantization of channel magnitude and channel direction in massive MIMO systems with correlated fading channels. To reduce feedback overhead, we adopt whitening method based on channel correlation, so the original channel is reduced to the effective channel with less dimensions. For quantization of the effective channel, we propose channel-correlation-based two-stage quantization and codebook design. Our simulation results show that our proposed limited feedback design significantly increases the average sum rate compared to the conventional limited feedback design with two-stage quantization.
