ABSTRACT:
A communication system is disclosed and it may include one or more first circuits in a first passband single carrier transmitter coupled to a first ultra-wide-band wireless transmission channel. The communication system may also include one or more second circuits in a first receiver coupled to the first ultra-wide-band wireless transmission channel. The one or more second circuits may enable receiving of signals transmitted by the one or more first circuits over the first ultra-wide-band wireless transmission channel at a baud rate less than or equal to half of a spectral bandwidth of the signal transmitted by the one or more first circuits. The one or more first circuits and the one or more second circuits coupled to the first ultra-wide-band wireless transmission channel may be a first piconet.
