EXPLOITINGTIMEDIVERSITYTO IMPROVEBLOCK SPREADOFDM INA MULTIPATHENVIRONMENT

Thispaper presents anewmethod toimprove onblock spread OFDM byexploiting timediversity toensure thattheblocks areindependent anduncorrelated ina multipath environment. WhileBSOFDM utilizes frequency diversity tosignificantly improve onOFDM in frequency selective channel, this didnotimprove during ftat fading channel whichdoesoccurduring transmission. Ourworkhasalsoshownthat this improvement isalsotrueinmultipath transmission. Byexploiting timeandfrequency diversity, BSOFDM isimproved significantly overconventional BSOFDMandconventional OFDM.'
