Abstract (en)

[origin: WO2020261176A1] To improve the spectral efficiency of TIBWB-OFDM, it is proposed a communication system that implements an alternative packing of the windowed OFDM component blocks that form a TIBWB-OFDM symbol. Adjacent windowed OFDM blocks are partially overlapped, instead of being juxtapose as in original proposed TIBWB-OFDM technique. Although the proposed packing method enables a highly efficient spectral transmission, this is achieved at the expense of intentionally introduced interference, by the transmitter, between consecutive sub-blocks that shape the TIBWB-OFDM symbol, which deteriorates the bit error rate performance. To cope with this additional interference, the receiver must entail both channel equalization and inter-block interference cancellation between OFDM component blocks of the TIBWB-OFDM symbol.
