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(jī)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複高斯白噪聲中對(duì)單頻複正弦信號(hào)頻率的估計(jì)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爲(wèi)高斯白噪聲信道和衰落信道、時(shí)變和時(shí)不變信道。

高斯白噪聲
Subsequently the channel was modeled for three types namely additive white Gaussian noise, flat fading and frequency selective fading.

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)用於差分跳頻(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(duì)採用無疊代譯碼及疊代譯碼的系統(tǒng)比特誤碼率(BER)上界進(jìn)行了理論推導(dǎo)及數(shù)值倣真騐証,竝與傳統(tǒng)的差分跳頻系統(tǒng)的性能進(jìn)行了比較。
