A cyclic correlation-based time domain channel estimation scheme

In the presence of guard band sub-carriers, the existing correlation-based time-domain channel estimation schemes do not perform well and suffer from high computational complexity. Herein, we proposed an optimized time domain channel estimation scheme with high accuracy and low complexity. In propos...
