This study describes reduced complexity demod-ulator of pulse-shaped spectrally efficient frequency division multiplexing signals (PS-SEFDM). It is based on using successive interference cancellation algorithm (SIC) with Viterbi tree. General expressions for estimation proposed presented. BER performance PS-SEFDM QPSK, QAM-16 the demodulation in AWGN considered. The same as one algorithm, while computational by more than 10 times case QAM-16.
An approach for improvement of bit-error rate (BER) performance spectrally efficient frequency division mul-tiplexing signals (SEFDM) with high order modulation in LTE fading channels is proposed. It based on using optimal pulse-shaped SEFDM symbols, lattice demodulation algorithm conjunction ZF equalizer the equivalent OFDM representation. Such reduces number adjacent sub carriers, which interfere each other channel. Therefore, algorithms, consider perform better. BER performances and...
