Adaptation beam formation and three-dimensional frequency block coded transmission mode for MIMO OFDMA system

摘要

Topic The radio communication system which augments reliability, is disclosed with this bill.SolutionsAs for this manner, (a) in start of the data frame, the step which gathers the metrics which displays channel state the channel concerning respectively and, (b) the step which allocates the transmission mode which corresponds to the lowest average bit error rate which 1 each mobile stations or the step which is allocated to the multiple communication channels and, (in every symbol of c) frame, calculated the respective average bit error rate of several transmission modes on the basis of the metrics which was gathered, concerning that symbol was calculated to that symbol and, (d) following to the transmission mode where each one is allocated, the step which transmits the symbol of the frameIt includes. Furthermore, bit loading optimization step can be run in order to decide modulation order in every symbol which it should transmit, interlocking with manner. Choice figure Drawing 1
