Abstract

System and method of ultra-wideband communication are provided. In one embodiment, an ultra-wideband communication system (22) divides a stream of data conveying symbols into a plurality of unspread subslreams (70). A common spreading code (38) is generated at the ultra- wideband transmitter, and each of the unspread substreams are spread using the common spread code to form a plurality of spread substreams (74). The spread substreams (74) are combined to form a composite signal (40) that is transmitted.
