An Efficient BPSK Modulation and Demodulation Scheme with the Complete
Removal of Fading
Abstract
A novel non-coherent BPSK modulation and demodulation scheme is
proposed to remove both slow and fast fading completely. We formulate a
compound function that reflects the different characteristics of both
slow and fast fading and prove that the scheme can remove fading from
the function completely. The scheme is reified by a simple architecture
that can remove slow and fast phase shifts completely from the received
signals. It is shown by using analytical model and numerical data that
the proposed scheme outperforms other ones significantly under the
presence of both slow and fast fading. The analytical results also show
that the proposed scheme can work well even with a small sampling rate,
resulting in a wireless device with low energy consumption.
