Description: 文章介绍了自适应均衡技术在MIMO OFDM系统中的应用研究。-In this paper, an adaptive channel
estimation for MIMO OFDM is proposed. A set of pilot
tones first are placed in each OFDM block, then the
channel frequency response of these pilot tones are
adaptively estimated by recursive least squares (RLS)
directly in frequency domain not in time domain. Then Platform: |

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.
