Abstract
A multichannel communications medium may have two or more channels available for transmitting information. A first transmission signal and a second transmission signal may be prepared from a same analog signal to be transmitted on a first channel and a second channel. For example, a phase shift or amplitude shift may be performed on the first transmission signal or the second transmission signal. The first transmission signal may be transmitted via the first channel, and the second transmission signal may be transmitted via the second channel. The phase shift or amplitude shift may be performed by analog components that are less complex than digital signal processors used for digital signal diversity. The analog components may be digitally controlled. The analog signal diversity may utilize cost effective analog components to improve the performance of the communications system over single channel communications without requiring complex digital signal processing of multiple signal paths.
