COMPUTER GENERATED SEQUENCES FOR DOWNLINK AND UPLINK SIGNALS IN WIRELESS COMMUNICATION SYSTEMS

摘要

The disclosure provides a base station transmitter (105), a user equipment transmitter and methods of operating the base station and user equipment transmitters. In one embodiment, the base station transmitter is for use with a cellular communication system and includes a synchronization unit (106) configured to provide a randomly-generated constant amplitude zero autocorrelation (random-CAZAC) sequence corresponding to a downlink synchronization signal. Additionally, the base station transmitter also includes a transmit unit (107) configured to transmit the downlink synchronization signal using the random-CAZAC sequence. In another embodiment, the user equipment transmitter is for use with a cellular communication system and includes a reference signal unit configured to provide a random-CAZAC sequence for an uplink reference signal corresponding to a one resource block allocation of the user equipment. The user equipment transmitter also includes a transmit unit configured to transmit the uplink reference signal using the random-CAZAC sequence.
