Channel Estimation and Hybrid Precoding for Millimeter Wave Cellular Systems
Channel Estimation and Hybrid Precoding for Millimeter Wave Cellular Systems
Millimeter wave (mmWave) cellular systems will enable gigabit-per-second data rates thanks to the large bandwidth available at mmWave frequencies. To realize sufficient link margin, mmWave systems will employ directional beamforming with large antenna arrays at both the transmitter and receiver. Due to the high cost and power consumption of gigasample …
