Abstract: A method of generating channel estimates of a communication channel in an OFDM system includes receiving references symbols from at least one time frequency observation block of a predetermined block size in frequency and time; generating subspace-transformed reference symbols from the received reference symbols; and subspace filtering the subspace-transformed reference symbols to generate a channel estimate for a communication channel target time; wherein 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.
