Abstract  Abstract

synchronous broadcast transmit the same broadcast content from a plurality of transmitters using the same waveform. transmitters are each the same for broadcast transmission using the extended code. when it has the division multiplex forward link in a spread spectrum communication system a synchronized broadcast transmission is inserted into a broadcast slot. One embodiment uses orthogonal frequency division multiplexing (OFDM) for the synchronous broadcast. OFDM receiver is then used to process the received synchronized broadcast transmission. an alternative embodiment realizes broadcast pseudorandom noise (PN) code used by the plurality of transmitters. then using the equalizer to estimate the synchronized broadcast transmission.

Synchronized broadcast transmits a same broadcast content using a same waveform from multiple transmitters. Transmitters each apply a same spreading code for broadcast transmissions. In a spread-spectrum communication system having a time division multiplexed forward link a synchronized broadcast transmission is inserted into a broadcast slot. One embodiment employs an Orthogonal Frequency Divisional Multiplex (OFDM) waveform for the synchronized broadcast. An OFDM receiver is then used to process the received synchronized broadcast transmission. An alternate embodiment implements a broadcast Pseudo-random Noise (PN) code for use by multiple transmitters. An equalizer is then employed to estimate the synchronized broadcast transmission.
