Abstract
A communications device configured to generate a first diversity signal comprising: a first single coded signal spanning a first frequency sub-band, and a second single coded signal contemporaneous with the first single coded signal spanning a second frequency sub-band offset from the first frequency sub-band such that the total bandwidth of the first diversity signal is greater than the bandwidths of either of the first and second frequency sub-bands alone; and a signal transmitter configured to transmit the first diversity signal to a first counterpart communications device; the first and second single coded signals each having properties such that, after undergoing a procedure comprising being: transmitted, received, shifted into a receiver frequency sub-band spanning a narrower bandwidth than the total bandwidth of the first diversity signal, and cross-correlated with a replica signal based on the transmitted signal, a single significant peak corresponding to the most direct transmission path is produced.
