a scheme of channel estimation using cyclic prefix based on the measurement of the low-voltage power line channel model is presented.after obtaining the frequency response of pilot sub-channel under the state of comb-type pilot,the data sub-channel response is obtained by interpolating the frequency response in frequency direction.in the pilot-free data period,the estimation of the channel is carried out by using cyclic prefix in order to improve the performance of system error rate.

摘 要：通过实际测量给出低压电力线的信道模型，在此基础之上提出了利用循环前缀对信道进行估计的方法，即在梳状导频模式时，使用导频获得导频子信道频率响应后，对其在频域方向进行插值得到数据子信道响应，在其后没有导频的序列的数据周期内，使用循环前缀对信道进行估计，从而起到改善系统误比特性能的目的。

Seizure frequency decreased by at least 50% in 47% of patients, by at least 75% in 24% of patients, and by 100% in 7% of patients. Of those receiving oxcarbazepine monotherapy, 59% had at least a 50% reduction in seizure frequency, 36% had at least a 75% reduction in seizure frequency, and 10% were seizure-free. Adverse events reported most frequently were dizziness in 46%, headache in 32%, fatigue in 30%, diplopia in 30%, nausea in 26%, abnormal vision in 21%, and somnolence in 21%.
