Analog-Digital Signal Processing for Multi-Channel Reception
In this paper an analog-digital signal processing scheme for multichannel signal reception with low-IF receivers is proposed and its performance is investigated. In the low-IF receivers, the signal in the mirror frequency causes interference to the desired signal. In the proposed analogdigital signal processing scheme, the interference signal is extracted with the analog filter and the interfer...
متن کاملAdaptive Prediction Iterative Channel Estimation for MC−CDMA Signal Reception in a Frequency Selective Fading channel
Abstract An adaptive prediction iterative channel estimation is proposed for the MC−CDMA signal reception in a frequency selective fading channel. Adaptive prediction filtering is incorporated into iterative channel estimation process and the filter tap coefficients are adaptively updated according to changes in the propagation environment. For channel estimation, the pilot MC-CDMA symbol is pe...
متن کاملAdaptive Prediction Iterative Channel Estimation for OFDM Signal Reception in a Frequency Selective Fading Channel
あらまし 本稿では,OFDM 受信における適応予測繰り返しチャネル推定を提案している.本方式は,繰り返しチャネル推定に適応 予測フィルタを導入して,そのタップ係数を伝搬環境の変化に適応して適応的に更新することに特徴がある.繰り返しチャネル推定の初 回では,周波数多重されているパイロットサブキャリアを用いて1次の内挿と外挿によりチャネル推定し,2 回目以降の繰り返しチャネル推 定では判定帰還,逆変調と適応予測フィルタを用いるチャネル推定を行う.適応予測フィルタのタップ係数の更新には,逆変調によって得 られた瞬時チャネル利得を参照信号とする正規化 LMS アルゴリズムを用いている.計算機シミュレーションにより,周波数選択性フェージ ング環境下でのビット誤り率(BER)特性を評価した.シミュレーション結果より,繰り返しチャネル推定は同じ BER を得るためのパイロットサ ブキャリア数を低減...
متن کاملAdjacent Channel Interference Cancellation Scheme for Low-IF Receiver in Multi-Channel Reception
In this paper a new adjacent channel interference (ACI) cancellation scheme for multi-channel signal reception with low-IF receivers is investigated through the experiment. In the low-IF receivers, the signal in the mirror frequency causes interference to the desired signal. In the proposed analog-digital signal processing scheme, channel selection is made by analog complex band pass filter and...
متن کاملTurbo Decoding Performance with Iterative Channel Estimation for Multi-channel Reception in Fast Rayleigh Fading
Coherent detection of received signals is required for turbo decoding. In this paper, we combine iterative channel estimation with Turbo decoding. Two combinations are considered in this paper. One is called outer-turbo channel estimation (OTCE), in which iterative channel estimation is carried out before turbo decoding. The other is called inner-turbo channel estimation (ITCE), in which channe...
