Advances in single carrier block modulation with frequency domain processing
This special issue focuses on single carrier block modulation (SC-BM) with frequency domain processing. This class of modulation and multiple access schemes complements the orthogonal frequency division multiple access (OFDMA) and its variations. For example, LTE (the long term evolution of the 3GPP standard), and LTE-Advanced, employ OFDMA in the downlink (base stations to mobiles) and SC-FDMA...
متن کاملFilter Bank Based Frequency Domain Equalizer in Single Carrier Modulation
This paper is concerned with the use of complexmodulated oversampled filter bank for frequency domain equalization in single carrier systems. A novel equalizer structure consisting of a low order linear phase FIR and an all-pass filter is applied in subband-wise compensation of channel amplitude and phase distortions separately. The performance of the proposed filter bank based frequency domain...
متن کاملSingle - Carrier Frequency Domain
rthogonal frequency division multiplexing (OFDM) has been recently adopted by major manufacturers and by standardization bodies for a wide range of wireless and wireline applications ranging from digital video/audio broadcasting to power-line communications. The major virtues of OFDM are 1) its resilience to multipath propagation providing a viable low-complexity and optimal (in the maximum lik...
متن کاملFrequency-Domain Block Signal Detection for Single-Carrier Transmission
One-tap frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can significantly improve the bit error rate (BER) performance of single-carrier (SC) transmission in a frequency-selective fading channel. However, a big performance gap from the theoretical lower bound still exists due to the presence of residual inter-symbol interference (ISI) after MMSE-FDE. ...
متن کاملFrequency Domain Equalization And Adaptive Ofdm Vs Single Carrier Modulation
In the present article an attempt is made to compare multi-carrier and single carrier modulation schemes for wireless communication systems with the utilization of fast Fourier transform (FFT) and its inverse in both cases. With the assumption that in OFDM (orthogonal frequency division multiplexing), the inverse FFT transforms the complex amplitudes of the individual sub-carriers at the transm...
