Title:
モード多重光通信システムの光受信装置及びプログラム
Document Type and Number:
Japanese Patent JP6814121
Kind Code:
B2
Abstract:
To provide a technology capable of reducing processing load in an optical receiver.SOLUTION: An optical receiver of a mode multiplexing optical communication system, includes: processing means for obtaining an inverse matrix of a channel matrix of the mode multiplexing optical communication system; and detection means for detecting the number of modes used in the mode multiplexing optical communication system. The processing means is configured to change the size of the inverse matrix in accordance with the number of modes detected by the detection means.SELECTED DRAWING: Figure 2
