Abstract  Abstract

This invention claims a method for carrying out data transmission by protecting sub-carrier and sub-carrier wireless device. whereby guard sub-carriers for data transmission method comprising: calibrating a multi-carrier orthogonal guard sub-carrier frequency division between adjacent frequency channels in multiplexing wireless system wherein adjacent radio frequency carrier is used to carrier radio signal through the adjacent frequency channels the plurality of guard sub-carriers can be identified for guard sub-carrier number of data transmission and to the preset physical resource units to be a unit the identified guard sub-carriers do not overlapped with the normal data sub-carriers of the radio signals. radio signal through the adjacent frequency channel transmission and reserving one or more of the identified guard sub-carriers such that the reserved one or more identified guard sub-carriers not used for data transmission. The invention provided guard sub-carriers for data transmission method and multi-carrier wireless device effect one can improve the overall system throughput and peak transmission rate.

A method of data transmi ssion over guard sub-carrier s is provided in a multi-carrier OFDM system. Adjacent radio fr equency (RF) carriers are used to carry radio signals transmitted through adjacent frequency channels. A plurality of guard sub-carriers between adjacent frequenc y channels are aligned and identified for data transmission in a pre-defined ph ysical resource unit. The identified guard sub-carriers do not overlap with normal da ta sub-carriers of the radio signals transmitted through the adja cent frequency channels. At least one of the identified guard sub-carriers is reserved as NULL sub- carrier. A flexible multi-carrier transceiver architecture is also provided in a multi-carrier OFDM system. Different multi-carrier and/or MIMO/SISO data transmission schemes are implemented by adaptively reconfigure same hardware modules including common MAC layer module physical layer entities and RF entities. Furthermore the flexible multi-carrier tr ansceiver architecture can be used to support data transmission over guard sub-carriers.
