Description: This paper introduces linear constellation precoding
(LCP) for OFDM transmissions over frequency-selective
fading channels. Exploiting the correlation structure
of OFDM subchannels, and choosing system parameters
properly, we first perform optimal subcarrier grouping
to divide the set of correlated subchannels into subsets.
Within each subset, a non-redundant constellation-specijic
unitary precoder is then designed to achieve maximum
multipath diversity and coding gains. While greatly reducing
the decoding complexity and simplifiing the LCP
design, subcarrier grouping offers optimal perjormance by
maximizing multipath diversity and coding gains. In addition,
the proposed system does not sacrifice the transmission
rate. Analytic evaluation and corroborating simulations
reveal its pe$ormance merits.

Description: 用小波变换思想,提出一种基于小波去噪的多输入多输出正交频分复用(MIMO-OFDM)系统信道估计方法。该方法首先利用最小二乘(LS)方法进行信道估计,然后对估计后的结果进行小波去噪处理。与传统最小二乘信道估计方法相比,该方法不需要预先知道信道的统计特性,信道估计性能有明显提高。-Based on wavelet transform,a method for MIMO-OFDM channel estimation with noise reduction is given,which is divided into DFT interpolation and noise reduction.Simulation experiments shows that,Compared with the traditional linear interpolation or DFT interpolation,the new method does not need any statistical characteristic of channel and it has good performance of channel estimation.

Description: dct precoded SLM method for PAPR reduction
High Peak to Average Power Ratio (PAPR) is still a
most important challenge in Orthogonal Frequency Division
Multiplexing (OFDM) system. In this paper, we propose a
Discrete Cosine Transform (DCT) precoding based SLM
technique for PAPR reduction in OFDM systems. This
technique is based on precoding the constellation symbols with
DCT precoder after the multiplication of phase rotation factor
and before the Inverse Fast Fourier Transform (IFFT) in
SLM-OFDM System.
