Unlike conventional MIMO-OFDMA, where users are separated in different frequency bands (subchannels), and each user is coded separately using STBC or SFBC, the proposed new scheme enables multi access by joint code design across multiple antennas, subcarriers, and users. Such system will benefit from the combined space and frequency domain freedom as well as multiuser diversity. Hence, better spectrum efficiency is achieved while improving bit error rate performance with respect to signal-to-interference ratio © 2012 GIRI.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Bit error rate (BER) performanceBlock processingCode designsDifferent frequencyError control codingFrequency domainsMIMO-OFDMMIMO-OFDMAMultiaccessMultiple antennaMultiuser diversityPermutation spreadingSignal to interference ratioSpectrum efficiencySub-carriersSubchannelsSystem complexityTransmission schemesCommunicationError detectionFrequency bandsFrequency selective fadingGain controlInnovationMIMO systemsOrthogonal frequency division multiplexingFrequency division multiple accessConference PaperCopyright : 2012 GIRI.
