  1. First, how to conduct sample and quantification of continuous time signal which is prior condition of sdr is explored in detail, and the comparison and analysis of some sample modes are given in which band pass signal sampling theorem is most important. second, multi - sample rate signal processing which is an important basis of sdr is studied. emphasis are put on decimation and interpolation those are the most fundamental process and the realization of decimation and interpolation filter

    在基於中頻采樣的軟體無線電結構框架下,首先詳細探討了軟體無線電的前提條件,即如何對連續時間信號進行采樣量化,比較分析了幾種采樣的方式,其中最為重要的是帶通信號采樣定理;然後探討了軟體無線電的一個重要基礎,即多采樣率信號處理,重點討論其最基本的兩個過程抽取和內插以及抽取和內插的實現;接著介紹了結構簡單、適用於一抽取的cic和適用於做2倍抽取的半帶;再論文在總結了傳統的調制解調基礎上,結合軟體無線電件的特點,系統的探討並實現了基於正交思想的am 、 fm 、 ask 、 fsk 、 bpsk 、 qpsk的正交調制解調演算法。
  2. Secondly, ground on the duct noise control, the delayed - lms algorithm, which is actulized easily, is brought forward, then the simulation on pc is achieved. it is shown from the computer simulation that for the single frequency noise, there will be a good effect when choosing the suitable parameters ; but for the narrowband noise, the effect will become worse with increasement of the bandwidth. this result is helpful to analyze the parameters influencing anc

    結果表明: ( 1 )隨著長度的增大,系統收斂速度變快; ( 2 )隨著值的增大,系統的收斂速度增大,但是當值超過某一范圍時會引起系統的發散; ( 3 )通路的延遲數與初噪聲頻率有關; ( 4 )對于窄帶信號, dlms演算法可以取得一定的降噪量,但是隨著窄帶信號帶寬的增大,降噪效果明顯變差。
