B-IFDMA - A Power Efficient Multiple Access Scheme for Non-frequency-adaptive Transmission

Paper i proceeding, 2007

Within the EU FP6 Integrated Projects WINNER and WINNER II, multiple access schemes for frequency-adaptive and non-frequency-adaptive transmission for a future broadband mobile wireless system are investigated. This paper presents a novel power effcient multiple access scheme for non-frequencyadaptive uplink transmission denoted Block Interleaved Frequency Division Multiple Access (B-IFDMA), which provides large frequency-diversity, potential power savings by user terminal sleep mode, modest high power amplifer backoff and robustness to frequency-offsets, and phase noise.
