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. The receive processor 452 implements various signal receive processing functions of the L1 layer.
