摘要： A method of wireless handover in a broadcast network (FIGS. 5 and 8) is disclosed. A wireless receiver (FIG. 4) receives a first signal (N) from a first transmitter (f1). The receiver measures a signal strength (RSSI) of the first signal. The strength of the first signal is compared to a first threshold (T0). The receiver receives a second signal (N+3) from a second transmitter (f3) in response to the step of comparing. The first and the second signals are sent to an application processor (120). The wireless receiver continues to receive the first and second signals until the application processor terminates receiving one of the first and second signals.

In one embodiment, the receiver includes a receive portion employing transmission signals from a transmitter having multiple antennas and capable of providing channel estimates. The receiver also includes a feedback generator portion configured to provide to the transmitter a pre-coder selection for data transmission that is based on the channel estimates, wherein the pre-coder selection corresponds to a grouping of frequency-domain resource blocks. The present invention also provides a transmitter having multiple antennas. In one embodiment, the transmitter includes a transmit portion coupled to the multiple antennas and capable of applying pre-coding to a data transmission for a receiver. The transmitter also includes a feedback decoding portion configured to decode a pre-coder selection for the data transmission that is fed back from the receiver, wherein the pre-coder selection corresponds to a grouping of frequency-domain resource blocks.
