Effect of low-precision quantization on the performance of channel estimation for OFDM systems

According to the cost and power consumption of wireless communication receiver under high-precision quantization, this paper discusses the effect on the performance of channel estimation for OFDM systems with low-precision quantization. Theoretical analysis and simulation results show that the low-precision quantization degrades the system performance. However, the optimized channel estimation algorithm can effectively reduce the impact of low-precision quantization on the performance of the channel estimation. Thus, this paper provides a reference to explore optimized channel estimation algorithms for OFDM system with low precision quantization.
