Abstract
An ultra-wideband (“UWB”) communication system comprising a transmitter and a receiver. In one embodiment, the symbol mapper circuit in the transmitter is adapted, in a first mode, to develop symbols having the number of pulses as currently defined in the 4z Standard; and, in a second mode, to develop symbols having fewer pulses than as currently defined in the 4z Standard. In an optional third mode, each data bit is mapped to a single pulse.
Claims16
A method for use in an ultra-wideband (UWB) transmitter, the method comprising the steps of:
- receiving n data bits;
- wherein n is a selected power of 2 greater than 1 and less than or equal to m;
- and
- wherein m is greater than 1;
- developing for each data bit a respective convolutionally encoded symbol;
- and
- mapping the symbol to m pulses of a packet;
- characterized in that the symbol is selectively mapped to (m÷n) pulses of the packet.
