Title: RECEIVER AND DATA RECEPTION METHOD
Abstract:
Provided in the embodiments of the present invention are a receiver and a data reception method. The receiver of the present invention comprises: two first input terminals for respectively receiving a digital signal with X polarization and a digital signal with Y polarization; a dispreading module for dispreading, according to N latency values and the spreading codes of N transmitters, the digital signal with X polarization and the digital signal with Y polarization, to acquire N first baseband signals and N second baseband signals, the N latency values being determined according to the difference between the synchronization position of the first polarization and the synchronization position of the second polarization of the N transmitters; a multiple-input multiple-output (MIMO) equalization module for performing an equalization filter processing on the N first baseband signals and the N second baseband signals to acquire the recovered data of the first polarization and the recovered data of the second polarization of the N transmitters. The embodiments of the present invention realize a coherent code division multiple access (CDMA) multipoint-to-point data transmission in an optical communication system.
