Abstract:
The receiver comprises a demodulator configured to detect a signal representing the OFDM symbols and to generate a sampled digital version of the OFDM symbols in the time domain. A Fourier transform processor is configured to receive the time domain digital version of the OFDM symbols and to form a frequency domain version of the OFDM symbols, from which the pilot symbol bearing sub-carriers and the data symbol bearing sub-carriers can be recovered. A detector is configured to recover the data symbols from the data bearing sub-carriers of the OFDM symbols and to recover the pilot symbols from the pilot bearing sub-carriers of the OFDM symbols in accordance with the continuous pilot symbol pattern. The continuous pilot symbols are present at the same sub-carrier locations in first OFDM symbols and as second OFDM symbols. A transmitter is also provided.

Claim (Index 26):
A method for recovering data from Orthogonal Frequency Division Multiplexed (OFDM) symbols, the OFDM symbols including a plurality of sub-carrier signals, some of the sub-carrier signals carrying data and some of the sub-carrier signals carrying pilots, the pilots comprising continual pilots, the continual pilots being distributed across the sub-carrier signals in accordance with a continual pilot pattern selected from a plurality of continual pilot patterns including a first continual pilot pattern and at least one second continual pilot pattern derived from the first continual pilot pattern, the method comprising:\n detecting a signal representing the OFDM symbols; generating a digital version of the OFDM symbols in a time domain, receiving the time domain digital version of the OFDM symbols and forming a frequency domain version of the OFDM symbols, from which the sub-carrier signals carrying pilots and the sub-carrier signals carrying data can be recovered, determining a number of sub-carrier signals in the plurality of sub-carrier signals; determining the continual pilot pattern of the OFDM symbols based on the number of sub-carrier signals; and recovering the data and the pilots from the sub-carrier signals.
