This estimation algorithm doesn't need any training sequences or pilot signal, therefore improves band efficiency and lower computational complexity.

这种估计方法不需要利用任何训练序列或导频信号，进一步提高了系统频带利用率，降低了计算复杂度。

When processing digital base-band, the signal of pilot-frequency was taken out from normal carrier channel and it would be used for transmitting pseudo pilot-frequency.

在数字基带处理时，从正常载频信道中提取出导频信号，用于伪导频的发射。

As in previous legs, lead singer Bruce Dickinson will be in the pilot's seat, flying the entire band and their roadies from city to city.
