ADDRESS FILTERING IN A RADIO FREQUENCY FRONT END OF A RECEIVER

摘要

A radio frequency (RF) front end receives one or more symbols of a first frame transmitted by a transmitter. The RF front end determines that the one or more received symbols are correlated to one or more address symbols, where the one or more address symbols are each a time-domain signal of subcarriers that the transmitter transmits. The RF front end provides the received one or more symbols to a baseband system based on the correlation. The baseband system recovers bits of a second frame within the first frame based on the received one or more symbols.
