<p>Techniques of channel correction and demodulation for orthogonal frequency division multiplexing (OFDM) systems are enhanced so that higher effective data rates and/or lower error rates can be achieved with a minimal processing load. Pilots are adaptively moved and/or removed, and their positions are changed, to enhance the channel estimation, decoding, and demodulation processes at the receiver. Reception is also enhanced by adding, removing, or changing the positions, of information-carrying data bits.</p> |
