This paper evaluates the performance of the proposed compressed sensing (CS) based channel estimator (CE) in fast fading channel with fractional delay. The channel impulse response (CIR) of the fast fading channel with fractional delay is changing over time where the number of impulses is dynamic resulting for the CE to be very complex. Fractional delay is a phenomenon when the receiver and transmitter have mismatch sampling which is very common in time domain CE. The simulation shows that proposed CE was able to estimate the fast fading channel with fractional delay with less error.
