摘要
The structure detection of sparse channel impulse response (CIR) is addressed in the frame of OFDM systems. Tap-tuned thresholds, exploiting a priori knowledge about the channel sparsity level (CSL), are designed to optimise the detection error probability. Compared to former proposed thresholds, the CSL-aware thresholds lead to higher CIR structure true detection rates and to lower channel response mean squares error.
