The BER performance of MIMO-SC-FDMA system may degrade quickly when the frequency-selective deep fading occurs in the channel. In order to solve this problem the IB-DFEIC (iterative block decision-feedback equalization & interference cancellation) algorithm applied in MIMO-SCFDMA system is proposed in this paper. In this algorithm the inter-layer interference and inter-symbol interference will...
The performance of the broadband wireless communication system with single carrier frequency domain equalization (SC-FDE) will be affected seriously by the tracking accuracy of frequency offset and timing offset. Especially when the length of the frame is high the frequency tracking must be very accurate. But in multi-path fading channel if the general frequency tracking loop is used the stable tracking...
The channel estimation accuracy has great impact on the bit error ratio performance of the single-carrier broadband wireless communication system. In order to enhance the channel estimation accuracy when the length of pilot is limited, a joint algorithm of iterative equalization and iterative channel estimation is proposed. This algorithm makes use of the iterative block feedback equalization (IB-DFE)...
Symbol timing estimation is one of key problems in OFDM systems. In this paper a new symbol timing estimation algorithm based on a training symbol is proposed. The study shows that the new algorithm is not affected by large carrier frequency offset basically. And it also has better performance than the previous timing estimation algorithm in terms of wrong probability. Through adopting this algorithm...
When all digital phase-locked loop (PLL) is applied in OFDM systems, there are two important problems that must be solved, namely how to normalize the error signal and how to avoid the phenomenon of out-of-lock in multipath fading channel. This paper has studied the two problems and put forward a suitable solution scheme. The studying results show that the proposed scheme can really effectively solve...
