Abstract

A generic re-transmission scheme is proposed for packet reservation multiple access (PRMA) assisted indoors cordless voice communications. Its frame error rate (FER) versus channel signal-to-noise ratio (SNR) performance is assessed under various traffic loading conditions using the example of a re-configurable transceiver. A significant operating SNR reduction can be achieved, if the traffic load is not excessive. This effect is particularly pronounced, if the speech transceiver used can drop its transmission rate and accommodate this lower rate using a more robust modem, when attempting re-transmission. The key system features are summarised
