頭條 基于變步長LMS的多普勒雷達回波信號處理方法 針對復雜電磁環(huán)境下多普勒雷達回波信噪比較低導致難以處理的問題，提出一種基于改進箕舌線函數(shù)的變步長LMS自適應噪聲對消方法。通過在原本的步長迭代公式和濾波器權系數(shù)迭代中添加反饋量來提高算法整體的抗干擾性能，在步長迭代中添加補償量來加快算法初期的迭代速度。仿真結果表明在0至-10 dB信噪比下，所提算法能夠有效還原含噪信號中的目標信號，誤差均方值最小為0.004 5，最大相關系數(shù)為0.95，最大輸出信噪比為10.60dB。實測結果表明所提方法在雷達回波信號降噪方面的性能突出，均方誤差最小為0.005 5，在實際電磁信號降噪處理中具有適應性和有效性。 最新視頻 江波龍嵌入式存儲eMMC,eMCP,fSD,tSD 核心功能：程序啟動分區(qū) / 增強區(qū)(enhanced area) / 后臺操作(Back ground operation)高級優(yōu)先中斷(HPI) / 增強型安全寫操作 發(fā)表于：5/6/2015 江波龍SSD存儲 江波龍推出M.2(NGFF)規(guī)格SSD，相比mSATA，M.2更小、更薄。產(chǎn)品支持32GB～128GB容量，分為S系列和B系列：S系列為SATA 6Gbps接口，滿足intel超級本SSD要求，適合應用在超級本中作為Storage;B系列是為Intel 平板平臺(如BayTrail-M)而設計的低成本SATAII SSD，價格比SATAIII SSD降低30%以上。 發(fā)表于：5/6/2015 【TI視頻】TI’s “Jacinto 6 Eco” drives outstanding performance for entry/mid-level infotainment systems Supports high-end features on entry/mid-level infotainment systems with DRA72x.
