摘要：A noisy frequency-domain channel estimate enhancer includes an over-sampler configured to transform the noisy frequency-domain channel estimate into a time-domain channel estimate that is virtually over-sampled by an integer factor m. The over-sampler is connected to a de-interleaver configured to divide the time-domain channel estimate into m de-interleaved sub-vectors. The de-interleaver is connected to a suppressor configured to suppress noisy taps from each de-interleaved sub-vectors to form m noi suppresd sub-vectors. The suppressor is connected to a lector configured to lect a noi suppresd sub-vector associated with a highest signal-to-noi ratio. The lector is connected to a discrete Fourier transformer configured to transform the lected noi suppresd sub-vector into a noi suppresd preliminary frequency-domain channel estimate. The discrete Fourier transformer is connected to a pha-shifter configured to pha-adjust the taps of the noi suppresd preliminary frequency-domain channel estimate to form an enhanced frequency-domain channel estimate.
