Systems and methods of ultra-wideband communication are provided. In one ultra-wideband communication method, a communication channel is divided into a plurality of non-overlapping sub-channels by dividing a single serial message intended for an ultra-wideband communication device into a plurality of parallel messages. Each of the plurality of parallel messages are then encoded onto at least some of the plurality of sub-channels, and then transmitted. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

What is claimed is: 1. A method of ultra-wideband communication, the method comprising the steps of: generating an ultra-wideband communication channel comprising a radio frequency channel segmented into a plurality of non-overlapping sub-channels; dividing a plurality of serial messages into a plurality of parallel messages; encoding each of the plurality of parallel messages onto at least some of the plurality of sub-channels; generating a bit stream for each non-overlapping sub-channel; shifting each bit stream in radio frequency by a radio frequency offset associated with each non-overlapping sub-channel; summing the shifted bit streams to generate a signal that occupies substantially all of the radio frequency band; and transmitting the plurality of parallel messages over the ultra-wideband communication channel, wherein the plurality of parallel messages are transmitted to a plurality of ultra-wideband communication devices. 2. A method of ultra-wideband communication, the method comprising the steps of: generating an ultra-wideband communication channel comprising a radio frequency channel segmented into a plurality of non-overlapping sub-channels; dividing a plurality of serial messages into a plurality of parallel messages; encoding each of the plurality of parallel messages onto at least some of the plurality of sub-channels; wherein each sub-channel comprises a radio frequency bandwidth that is defined by: description="In-line Formulae" end="lead"b=(1+r)/Tdescription="In-line Formulae" end="tail" where b=a radio frequency bandwidth for each of the plurality of sub-channels, and r=a roll-off factor, and T=a symbol duration for each of the plurality of non-overlapping sub-channels, wherein the roll-off factor is selected so that M is approximately an integer in: description="In-line Formulae" end="lead"M=N(1+r); anddescription="In-line Formulae" end="tail" transmitting the plurality of parallel messages over the ultra-wideband communication channel.
