Title:
不均等サブキャリア間隔を用いるマルチキャリアチャネルの到達距離拡張
Document Type and Number:
Japanese Patent JP7073884
Kind Code:
B2
Abstract:
Methods and systems for reach extension of multi-carrier channels using unequal subcarrier spacing may decrease FWM by grouping the subcarriers into groups of 2 subcarriers, and apply a secondary, unequal spacing between the groups. In this manner, nonlinear interactions may be reduced and the transmission reach of a multi-carrier channel may be extended.
