摘要
In massive MIMO systems, multiple high-speed high-resolution ADCs will be a major obstacle for real applications because of the hardware complexity and power consumption. One solution to this problem is to adopt low-cost low-resolution ADCs instead. Note that highly quantized signals will destroy the orthogonality of OFDM design, the key point remains to find computational decoding methods while maintaining acceptable performances. To address this issue, we develop a low complexity algorithm designed for low-resolution ADCs RF-frontend using iterative decoding based on Approximate-Message-Passing (AMP). The proposed algorithms can provide adequate performance in low-resolution ADC systems compared to approximate LMMSE solution.
