Title: OFDM-BASED IMPLEMENTATION OF BLOCK-WISE SINGLE CARRIER WAVEFORM (BWSC)
Abstract:
Methods and architectures for block wise single carrier implementation using orthogonal frequency division multiplexing (OFDM) include scheduling a users transmission of a plurality of quadrature amplitude modulated (QAM) data symbols to be sent at a subband within a limited plurality of subbands of an available frequency bandwidth to provide multiple user access across the limited plurality of subbands. Spectrum shaper circuitry applies discrete Fourier transform (DFT) shaping filtering and subband scheduling filtering in a frequency domain single carrier signal. An inverse fast Fourrier transform (IFFT) circuit transform blocks of the frequency domain single carrier signal into an orthogonal frequency division multiplexed (OFDM) waveform to enable over the air transmission of the QAM data symbols as a block wise single carrier (BWSC) data symbol.
