Pilot-aided multipath delay spread approximation for MMSE channel estimation in OFDM systems

Minimum mean square error (MMSE) channel estimation in OFDM systems requires knowledge on channel correlation function. For systems with a small number of pilots operating in time-varying channels, however, information on channel correlation is difficult to acquire. In this paper, instead of estimat...
