Algorithm of channel estimation using special training sequence for MIMO-OFDM systems;

Algorithm analysis of timing synchronization for OFDM system based on training sequences;

Large estimation range and precise estimation can be acquired by the new method by twice frequency offset estimation;moreover,date transmission efficiency will be improved without any demand for training sequences.

In this paper,we analyzed the channel estimation base on block-type training sequences for the typical UWB indoor channel model.

11a system,the coarse frame synchronization can be realized with auto-correlation posed by the periodicity of short training sequences,and the fine frame synchronization can be implemented using cross-correlation between local short training sequences and received signals.

Channel estimation and tracking using implicit training;

In this paper, the performance of implicit training assisted 16QAM is investigated on different factors such as the length of training sequence, power allocation between training and data sequence, the length of the first-order statistics, etc.
