Abstract:
    The method includes that: estimates the channel impact response of the mid training queue of the sub-frame normal slot; against the data section in the normal slot, according to the distance between the mentioned data section and the mentioned mid training queue, calculating via interpolation the channel impulse response of the mentioned data section. The invention avoids that treats directly the channel impulse response of the mid training queue is treated directly as the channel impulse response of the data section. This ensures a more accurate channel estimation of the data section and solves the technical problem that the channel estimation under hi-speed condition is difficult to realize via the existed technique. Therefore, the effective cover of the net against the hi-speed railway is realized.
