Uplink pilot multiplexing in SU-MIMO and SDMA for SC-FDMA systems

Abstract

The invention claims supporting self-adaptive uplink pilot frequency multiplexing method system and method for. The implementing example according to multi-plexing flow of the number of such as the uplink channel data frequency location and pilot frequency channel bandwidth of the block in time automatically adapt the variation. So that the invention claims a self-adaptive uplink pilot frequency multiplexing scheme can provide flexible the uplink pilot frequency allocation scheme while maintaining single carrier wave shape so as to improve emission power efficiency and the pilot frequency of orthogonality to improve the channel estimation and restraining interference.
