The receive processor 412 performs various signal receive processing functions for the L1 layer (i.e., the physical layer) including decoding, deinterleaving, descrambling, demodulation, depredialing, and physical layer control signaling extraction, among others. The transmitter 416 is configured to convert the baseband signals provided by the transmit processor 415 into rf signals and transmit the rf signals via the antenna 420, and the receiver 416 is configured to convert the rf signals received by the antenna 420 into baseband signals and provide the baseband signals to the receive processor 412.

On the receive side, each receiver 456 receives a radio frequency signal through its respective antenna 460, and each receiver 456 recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to a receive processor 452.
