基本解釋

Propabilities of false alarm and acquisition of the system in white gaussian noise are discussed.
文中分析了在白高斯隨機噪聲情況下，系統(tǒng)的虛警概率和捕獲概率。
A method for estimating the frequency of a complex sinusoid in additive complex white Gaussian noise is proposed.
本文提出了一種在加性復(fù)高斯白噪聲中對單頻復(fù)正弦信號頻率的估計方法。
According to different channel models, CDMA systems can be divided into additive white gaussian noise (AWGN) channel and dispersive channel, time-variant and time-invariant channel.
CDMA系統(tǒng)按信道模型的不同分為高斯白噪聲信道和衰落信道、時變和時不變信道。

Subsequently the channel was modeled for three types namely additive white Gaussian noise, flat fading and frequency selective fading.
接下來信道建模成三種不同的類型，即加性高斯白噪聲信道、平坦衰落信道和頻率選擇性衰落信道。
白高斯噪聲
The bit-interleaved coded modulation(BICM) technique is applied to the differential frequency hopping(DFH) system. Bit error rate(BER) upperbounds corresponding to noniterative decoding and iterative decoding are derived,over both the additive white Gaussian noise(AWGN) channel and the frequency nonselective Rayleigh fading channel.
將比特交織編碼調(diào)制(BICM)技術(shù)應(yīng)用于差分跳頻(DFH)通信系統(tǒng),在加性白高斯噪聲(AWGN)信道及頻率非選擇性瑞利慢衰落信道下,對采用無迭代譯碼及迭代譯碼的系統(tǒng)比特誤碼率(BER)上界進行了理論推導(dǎo)及數(shù)值仿真驗證,并與傳統(tǒng)的差分跳頻系統(tǒng)的性能進行了比較。
