Method and apparatus for mobile broadcast and multicast using randomized transmit signal phases in a single frequency network |
摘要 |
A base station transmitter for a broadcast/multicast single frequency network may include a base station component configured to randomize a phase of the signal for the base station transmitter to transmit, wherein the base station transmitter is configured to transmit a signal having a frequency common to a frequency of a signal sent by another base station component in the network. A method for improving performance of single frequency networks may include transmitting single frequency signals from base stations with pseudo-random phases including in the signals, data that permits a receiver compatible with the network to synchronously replicate the pseudo-random phases used in the transmission of the single frequency signals. |
