Fast Frequency Hopping Using Code Division Multiplexing Pilot in an OPDMA System |
| abstract |
Techniques are provided to support fast frequency hopping with code division multiplexed (CDM) pilot in a multi-carrier communication system (eg, OFDMA system). Each transmitter (eg, each terminal) in the system transmits a wideband pilot on all subbands, allowing the receiver (eg, base station) to estimate the overall channel response simultaneously. A wideband pilot for each transmitter may be generated using direct sequence spread spectrum processing and based on a pseudo random number (PN) code assigned to that transmitter. This allows the receiver to individually identify and recover multiple broadband pilots transmitted simultaneously by multiple transmitters. In a time division multiplexing (TDM) / CDM pilot transmission scheme, each transmitter transmits a wideband pilot in bursts. In a continuous CDM pilot transmission scheme, each transmitter transmits a wideband pilot continuously despite a low transmit power level. Any frequency hopping rate may be supported without affecting pilot overhead. |
