Title:
デジタル通信装置によって生成された干渉を減少させるシステムおよび方法
Document Type and Number:
Japanese Patent JP4024859
Kind Code:
B2
Abstract:
A system and method for reducing radio frequency interference arising in connection with pulsed transmission over time division multiplexed communication channels. In a first embodiment, a subscriber station is nominally assigned all of the slots of each frame of a first transmit channel. By transmitting RF energy substantially continuously, the subscriber station reduces interference arising from pulsed transmission. In a second embodiment, a subscriber station is nominally assigned one or more slots of each frame of a primary channel for conventional transmission of useful information, and is also instructed to continuously transmit RF energy over an auxiliary channel at times other than during the assigned primary channel slots. In this way, interference generated in the vicinity of the subscriber station is reduced due to the substantially continuous transmission of RF energy by the subscriber station. More than one subscriber station may simultaneously utilize the auxiliary channel during reduced interference mode operation.
