ABSTRACT:
Apparatus and methods of ultra-wideband (UWB) communication are provided. In one embodiment, an ultra-wideband transmitter includes a processor configured to generate data for transmission in the form of a plurality of ultra-wideband pulses. The transmitter includes a FEC encoder that generates a code word based on the data. The FEC includes a plurality of cyclic shift registers configured to receive and process the data, a plurality of fixed connections between each of the plurality of cyclic shift registers and a plurality of XOR gates communicating with the plurality of fixed connections. 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.
