L-M算法。除了動(dòng)量法(基于梯度下降的訓(xùn)練算法)外,學(xué)習(xí)率自適應(yīng)調(diào)整策略是BP算法改進(jìn)的另一種途徑,它利用Levenberg-Marquardt優(yōu)化方法,從而使得學(xué)習(xí)時(shí)間更短。其缺點(diǎn)是,對(duì)于復(fù)雜的問(wèn)題,該方法需要很大的存儲(chǔ)空間。

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain

手機(jī)文件瀏覽程序的另外一個(gè)版本! SMan is a system utility that manages your UIQ device. It provides functionality which manufacturers did not provide or which are difficult or impossible to do manually. SMan helps keep your UIQ device running in a "healthy" state and, to a certain degree, allows you to customize the system behaviour of your device.

考慮L的三個(gè)不同值:L=256(3個(gè)數(shù)據(jù)段),L=128(7個(gè)數(shù)據(jù)段)和L=64(15個(gè)數(shù)據(jù)段)。各自的譜估計(jì)圖如上圖所示。可以明顯的看到,加窗明顯的減小了頻譜上的假譜峰,但也更加進(jìn)一步平滑了譜峰。所以,對(duì)于L=64的情況,在ω=0.8π的譜線可以很確定的辨認(rèn),但是那兩個(gè)靠近的譜峰不容易區(qū)分。對(duì)于L=128的情況,這種情況提供了在分離和檢測(cè)間最好的均衡。當(dāng)然,對(duì)于在L=256時(shí)的情況,效果是更好的,能夠從譜估計(jì)圖上明顯的分辨出三條譜線的存在以及它們幅度關(guān)系的強(qiáng)弱。 除了Welch法外,還可以采用對(duì)多個(gè)周期圖求平均的功率譜估計(jì)方法的其他方法如Bartlett法等等,在功率譜估計(jì)上也能取得較好的結(jié)果。
