Abstract
A wireless communication system for demodulating data packets includes an interface circuit and a modem circuit. The interface circuit may receive a data packet, and the demodulator circuit may demodulate a first part of the data packet by dispreading only selected data bits in the data packet. The demodulator circuit may separately process at least a data payload portion of the data packet without dispreading.
