• 論文の詳細を見る

• A modified sequential acquisition scheme is proposed in this letter to avoid the significant high error probabilities(false alarm and missing probabilities)occurring with the conventional sequential acquisition scheme in direct-sequence spread-spectrum systems while a high frequency offset is present. A new estimator of E_K/N_O is also designed to effectively solve the problems caused by the channel fading effects. Extensive computer simulation results have indicated that the proposed technique can achieve the desired low error probabilities, and furthermore its performance is very close to that with the perfect channel estimation.
