頭條 基于FPGA的梳狀譜通信干擾信號(hào)設(shè)計(jì)與研究 為了有效測(cè)試通信電臺(tái)的實(shí)際抗干擾性能，提出了一種基于FPGA的高斯白噪聲梳狀譜干擾信號(hào)設(shè)計(jì)方案，相比傳統(tǒng)隨機(jī)相位調(diào)頻梳狀譜干擾，在對(duì)抗寬帶通信系統(tǒng)時(shí)干擾效果更強(qiáng)。該方案以FPGA為核心，通過(guò)改進(jìn)Ziggurat算法和DDS技術(shù)實(shí)現(xiàn)梳狀譜干擾信號(hào)的生成，在滿(mǎn)足高速、高性能的同時(shí)，具有較強(qiáng)的靈活性。并通過(guò)DA芯片輸出，實(shí)現(xiàn)了3~11個(gè)梳狀譜信號(hào)的生成。實(shí)驗(yàn)結(jié)果表明：生成的梳狀譜干擾信號(hào)頻率控制誤差小于0.001%，干擾效果量化一個(gè)指標(biāo)。 最新視頻 江波龍嵌入式存儲(chǔ)eMMC,eMCP,fSD,tSD 核心功能：程序啟動(dòng)分區(qū) / 增強(qiáng)區(qū)(enhanced area) / 后臺(tái)操作(Back ground operation)高級(jí)優(yōu)先中斷(HPI) / 增強(qiáng)型安全寫(xiě)操作 發(fā)表于：5/6/2015 江波龍SSD存儲(chǔ) 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(mǎn)足intel超級(jí)本SSD要求，適合應(yīng)用在超級(jí)本中作為Storage;B系列是為Intel 平板平臺(tái)(如BayTrail-M)而設(shè)計(jì)的低成本SATAII SSD，價(jià)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.
