DIVERSITY RECEPTION

摘要

A receiver for receiving signals of a protocol in which traffic data is redundantly modulated onto both of two carriers according to a predetermined decision scheme, the receiver comprising: an input for receiving signals on the two carriers; a demodulator for demodulating the signals received on each of the two carriers to form two respective received data streams; first transformation logic for generating a first candidate set of traffic data by processing the received data streams by the functional inverse of the predetermined decision scheme; second transformation logic for generating a second candidate set of traffic data by aggregating corresponding bits of each of the received data streams; and a traffic data set selector for selecting data from either the first candidate set of traffic data or from the second candidate set of traffic data for further processing, the traffic data set selector being configured to make that selection in dependence on the relative strength with which signals on the two carriers are received.
