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: OFDM is multicarrier modulation (MCM) technique which provides an efficient means to
handle high speed data streams on a multipath fading environment that causes ISI. Normally
OFDM is implemented using FFT and IFFT’s. To decrease the BW waste brought by adding
cyclic prefix, wavelet based OFDM is employed.-OFDM is multicarrier modulation (MCM) technique which provides an efficient means to

Description: Here, wavelets are used in Orthogonal frequency division multiplexing. Wavelets are small waves having amplitude increase starting zero and reduces back to zero. In conventional OFDM, IFFT is used at the transmitter side and FFT is used at receiver. In case of Wavelet OFDM, IFFT is replaced with IDWT and DWT is used instead of FFT. In OFDM cyclic prefix is added to reduce inter channel interference and inter carrier interference. By using wavelet transform, cyclic prefix is not needed. Hence, it has high spectral efficiency. Wavelet transform the signal one domain to time and frequency domain. -Here, wavelets are used in Orthogonal frequency division multiplexing.
