Patent ID: 7305057

Claim:
A multichannel filter-based handheld ultra Wideband (UWB) communication transmitter comprising: A convolution encoder coupled to a block interleaver; the block interleaver coupled to a multichannel pseudorandom (PN) sequence mapping; the multichannel PN sequence mapping coupled to a digital UWB transmitter filter system; the digital UWB transmitter filter system coupled to a digital-to-analog (D/A) converter; the D/A converter coupled to a multichannel-based multicarrier modulator; the multichannel-based multicarrier modulator coupled to a power amplifier (PA); a PN sequence look-up table coupled to the multichannel PN sequence mapping; a multichannel control coupled to the multichannel PN sequence mapping and coupled to the multichannel-based multicarrier modulator; and a clock control coupled to the digital UWB transmitter filter system, the D/A converter, and the multichannel-based multicarrier modulator.
