ADC Online Clustering Aided Minimum Weighted Hamming Distance Detection for MU-MIMO Systems with Low Resolution ADCs and Apparatus Therefor

摘要

Disclosed is a method and apparatus for detecting data based on a minimum weighted Hamming distance using an online cluster analysis technique in a multi-antenna communication system using a low-resolution ADC. A data detection method according to an embodiment of the present invention is a data detection method in a receiver of a multi-antenna communication system using a low-resolution analog-to-digital converter, the method comprising: receiving data transmitted from a transmitter; Learning channel information using pilot symbols of the received data; Updating channel information that changes in time based on the learned channel information; And detecting the data in real time based on the updated channel information, wherein the updating of the channel information includes a codeword corresponding to the channel information and a crossover probability based on the learned channel information. probability), and the channel information may be updated based on the updated codeword and a crossover probability.
