1. A modulation method comprising:
- dividing a series of data bits into a plurality of contiguous blocks;
composing each said block into a corresponding parallel packet;
mapping one or more bits from each said parallel packet into a corresponding data symbol; and
modulating said data symbols onto respective subcarriers of an OFDM symbol.

10. A demodulation method comprising:
-
demodulating a first predetermined number of OFDM symbols to form a second predetermined number of parallel symbol streams, each said symbol stream comprising the first predetermined number of symbols; de-mapping each said parallel symbol stream to a corresponding packet; decomposing each said packet into a contiguous block of a series of data bits. - View Dependent Claims (11, 12)
