Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A receiver configured to recovering data from Orthogonal Frequency Division Multiplexed (OFDM) symbols, wherein the OFDM symbols include a plurality of sub-carrier signals, some of the sub-carrier signals carrying data symbols and some of the sub-carrier signals carrying pilot symbols, the pilot symbols comprising continuous pilot symbols, the continuous pilot symbols being distributed across the sub-carrier signals in accordance with a continuous pilo…
