Fractionally-sampled blind channel estimation for a mobile communication system
Hideo Murakami · 2008
This paper introduces a blind channel estimation method for a block transmission system in which symbols are transmitted in blocks. In most of digital communication systems, low-pass filters are placed at a transmitter to confine the transmitting waveform to an allocated bandwidth and at a receiver to improve signal-to-noise power ratio. Consequently, if the received waveform is sampled with sufficiently fast rate, the resulting discrete-time signal is band-limited and exhibits a smooth waveform.
