Soft handover system for a multiple sub-carrier communication system and method thereof

摘要: A soft handover system is provided for a multiple sub-carrier communication system, applicable to the uplink (mobile unit base stations) and/or downlink (base stations mobile unit). The uses sub-carriers simultaneously transmit signals between at least two and in downlink. In certain embodiments, provides synchronized transmission such that delay differences transmissions from different arriving are within guard time of symbols. Certain embodiments use same set links cells, other sets cells. using sub-carriers, receives with identical data content stations. need not distinguish just treats as multipath components, thereby increasing diversity gain. case CDMA can well encoding spreading code.
