Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) is considered as a promising equalization technique for a broadband single-carrier (SC) transmission. When a square-root Nyquist filter is used at a transmitter and receiver to limit the signal bandwidth, the presence of timing offset produces the inter-symbol interference (ISI) and degrades the bit error rate (BER) p...

The automatic upgradation of equalizer weights in channel equalization demands a low-complexity, highly accurate estimation recovery at the minimum possible time. low-complexity frequency domain improves mean square error (MMSE) process. Adding superiority particle swarm optimization (PSO) to coefficient selection process enhances MMSE. This work proposes frequency-domain along with modified PS...

Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion is a powerful equalization technique for the broadband single-carrier (SC) transmission. However, the presence of timing offset produces the inter-symbol interference (ISI) and degrades the bit error rate (BER) performance. As the roll-off factor of the transmit filter increases, the performance degrades mor...

| In recent years single carriermodulation (SCM) has again become an interesting and complementary alternative to multicarrier modulations such as orthogonal frequency division multiplexing (OFDM). This has been largely due to the use of nonlinear equalizer structures implemented in part in the frequency domain by means of fast Fourier transforms, bringing the complexity close to that of OFDM. ...

In this paper, we propose, based on the analytical analysis of the received signal for single carrier overlap frequency domain equalizer (SC-OFDE) equalization, an optimum design of the overlap frequency domain equalization. From the estimation of the received signal-to-interference-and-noise-ratio (SINR), we propose an algorithm that automatically adapts one important parameter of the OFDE equ...

Per tone equalization has been proposed in 6] 7] as an alternative to time domain equalization for DMT-based systems. In this paper, an iterative initialization scheme based on so-called RLS with inverse updating is presented for these equalizers. Simulation results show convergence with an acceptably small number of training symbols. Complexity calculations are made for per tone equalization a...
