A least-squares (LS) channel estimation (CE) technique for mobile orthogonal frequency-division multiplexing (OFDM) communications over a rapidly time-varying frequency-selective fading channel is investigated in this paper. The proposed technique keeping the comb-type pilot arrangement can achieve a lo...
OFDM时变衰落信道分解信道模型Viterbi算法There exist Inter-Carrier Interference (ICI) phenomena when OFDM signals are transmitted through time-varying fading channels. The performance of communication systems also decreases. Based on decomposing of time-varying fading channels, the system can be treated as...

We derive a key performance measure parameter to evaluate the overall feedback control performance over narrowband channels. We show that fading can result in considerable delay and/or poor performance of the mobile sensor depending on the system requirements. To improve the performance, we then ...
