[Program doc] RAKE DL : 0: ：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.

[Other] THE3 DL : 0: a Matlab code that produces a plot of probability of bit error rate for QPSK versus SNR for three receive antennas, and three different combining methods: MRC, equal gain combining, and selection combining. The plot is generated by using Monte Carlo simulation. The SNR in this plot is the single-antenna average signal-to-noise ratio, and range from -5 dB to 15 dB.
