Improving recovered signal quality in TETRA systems

This whitepaper considers the factors that modern communication systems must overcome to decode a voice or a data message and the use of triple diversity receiver design, in contrast with dual diversity with equalization techniques, to ensure the reliable recovery of transmitted digital signals.

To ensure the reliable recovery of transmitted digital signals, modern communication systems must overcome a number of factors affecting the signal's propagation through space, causing the signal to noise ratio (SNR) to degrade and, consequently, compromising the radio's ability to decode a voice or a data message.

A number of techniques exist that help overcome these distortions. The first approach advocates use of a triple diversity receiver design, while the second argues for dual diversity in tandem with equalization techniques.
