Description: This code was used for making the practical measurements in section 2.3 of my thesis. This Matlab code allows an OFDM signal to be generated based on an input data file. The data can be random data, a grey scale image, a wave file, or any type of file. The generated OFDM signal is stored as a windows wave file, allowing it to be viewed, listened to and manipulated in other programs. The modified wave file can then be decoded by the receiver software to extract the original data. This code was developed for the experiments that I performed in my honours thesis, and thus has not been fully debugged.
This is the original code developed for the thesis and so has several problems with it. The BER performance given by the simulations is infact Symbol Error Rate.

Description: :首先介绍了DS--UWB系统的的发射与接收模型,然后分析了利用滑动相关法对信道进行估讣,并巾此给出
了不同RAKE接收机RAKE合成权系数选取方案。对接收机采用最大比(MRC)、最小均方误差(MM SE)及带均衡
器的(MRC)合并系数选取的误码性能进行了仿真和对比。结果表明了带均衡器的MRC—RAKE只用较少的分支
就可以达到接收性能明显优于MMSE—RAKE的程度。尤其在信噪比比较大时。这种优势更加明显。-: First of all, the introduction of the DS UWB system model of the launch and reception, and then analyzed using the sliding correlation method for estimation of channel obituary, and towels, this gives the RAKE receiver RAKE synthesis of different weights to select the program. On the receiver using maximal ratio (MRC), minimum mean square error (MM SE) and band equalizer (MRC) combined coefficient selected BER simulation and comparison. The results show that the equalizer with MRC-RAKE only with fewer branches on the receiver performance can be achieved significantly better than MMSE-RAKE level. Particularly in the relatively large signal to noise ratio. This advantage becomes even more evident. Platform: |
