Energy Efficient Transmitter Power Control

Abstract

A microwave transceiver including a data buffer, an ACM module, a PA and an antenna. The ACM module is configured to receive the buffered data from the data buffer and modulate the buffered data in a spectrally efficient modulation format, and the PA is configured to receive the modulated buffered data from the ACM module and transmit it at output power to the remote microwave transceiver via the antenna Amplified modulation buffer data. The modulation format is selected from a plurality of modulation formats based on a feedback signal from a remote microwave transceiver. The microwave transceiver also includes a control module configured to monitor a buffer status of the data buffer and to control output power of the PA based on the buffer status.

Description

technical field [0001] The present disclosure relates to wireless communication systems, and more particularly to transmitter power control for point-to-point microwave radio links implementing Adaptive Coding and Modulation (ACM). Background technique [0002] A microwave radio link or radio link system is a communication system that transmits data between two fixed locations via a point-to-point link. A microwave radio link transmitter and receiver are usually included in one unit, denoted here as a microwave transceiver. [0003] Radio transmissions such as microwave radio transmissions often interfere with adjacent communication systems. If microwave radio transmissions are strong enough, this interference can degrade the performance of adjacent communication systems, at least where the spectrum overlaps. Therefore, it is desirable to reduce radio interference in wireless communication systems. [0004] Power consumption is a significant contributor to the cost of the...
