Weighting windows may have effect on the estimation performance of signal frequency, thus modified window scaling WSC (WSC) should be used for revising the error. Frequency estimation accuracy varies with different position between two samples in spectrum when the frequency of a tone is contaminated with noise. Only considering bias and root mean square error (RMSE) at each position cannot give a...
Interference reduces the performance of a correct data signal detection and decoding. This problem becomes severe when interferences exist during the period of channel estimation. This will destroy the accuracy of channel estimation and, will eventually result severe degradation in the performance of signal detection and decoding in the entire data packet/frame. In this article, we propose an improved...
In this paper, a new channel estimation method is proposed for channel estimation in the 3GPP LTE downlink. The channel estimation is first implemented in the time-domain before selecting the dominant channel taps to improve the signal to noise ratio (SNR) by ignoring the taps corresponding to the lower powers. In the frequency-domain, the transformed channel data corresponding to the pilot positions...
In this paper we present the evaluation of a receiver signal processing chain for a 3GPP long term evolution (LTE) terminal, including coarse synchronisation, channel estimation, fine syncronisation (tracking), MIMO equalization and detection. Algorithm blocks are first individually explained and simulatively evaluated with a realistic channel model. Adjustments of the blocks to each other for improved...
