Fast and reliable channel estimation is very important for wireless communication transmission. A novel One-Cycle blind channel estimation algorithm based on cyclostationarity properties of OFDM signal is proposed in this paper. Without changing cycle frequency, the new algorithm is formed from using the two related z-transform values of delay parameter. Furthermore, a simplified algorithm based on...
We introduce a novel channel impulse response (CIR) estimation method to improve performance of conventional frequency-domain pilot and time-domain processing (FPTP) algorithm. In practical OFDM system with virtual subcarriers, the conventional FPTP algorithm can effectively reduce CIR estimation error caused by band-limitation effect but it has a limit on reducing the error if the first estimation...
Orthogonal Frequency Division Multiplexing has become a key element of todays wireless communication systems. However, its sensitivity to oscillator phase noise is responsible for common phase error (CPE) and inter-carrier interference (ICI) which greatly degrades the overall system performance. In this contribution, we address the problem of reducing the effects of phase noise in an OFDM system operating...
