Abstract: A method of generating channel estimates of a communication channel in an OFDM system includes receiving reference symbols from at least one time-frequency observation block of a predetermined block size infrequency and time. Subspace-transformed reference symbols are generated from the received reference symbols. The subspace-transformed reference symbols are subspace filtered to generate a channel estimate for a communication channel target time. A latency between a communication channel time instant of a currently received reference symbol and the communication channel target time is smaller than the observation block size in time.
