研究目的
Investigating the achievable rate of indoor THz communication systems equipped with finite-bit ADCs at user sides.
研究成果
The study concludes that the achievable rate of indoor THz communication systems with finite-bit ADCs is robust to the transmit power and mainly depends on the distortion parameters. The rate loss caused by phase uncertainties can be negligible in large subarray antenna regime.
研究不足
The study focuses on the indoor THz communication systems with finite-bit ADCs at user sides and does not consider outdoor scenarios or other types of receivers.
1：Experimental Design and Method Selection:
The study employs hybrid precoding with MRT and ZF precoding at the baseband, considering the array of subarray antenna structure.
2：Sample Selection and Data Sources:
The analysis is based on the indoor THz channel model and the hybrid beamforming scheme.
3：List of Experimental Equipment and Materials:
The system model includes finite-bit ADCs at the receiver and infinity-resolution DACs at the transmitter.
4：Experimental Procedures and Operational Workflow:
The study derives the closed-form expression of the lower bound of the achievable rate when the number of subarray antennas goes to infinity.
5：Data Analysis Methods:
The impact of quantized receivers and phase uncertainties on the system performance is analyzed.
