US Patent 7796574 Multi-carrier reception for ultra-wideband (UWB) systems

System and method for receiving transmissions in a wireless communications system. A preferred embodiment comprises a receiver (such as receiver 400) that can despread and then demodulate a symbol from a transmitter that first spread and then modulated the symbol. By reversing the processing order, the demodulation can be performed at a lower data rate and therefore reducing computational and power requirements.
