Abstract
A method of encoding a first bit and a second bit for transmission on a transmission band is provided. The method includes: mapping, via a mapping component, the first bit and the second bit into a first symbol; mapping, via the mapping component, the first bit and the second bit into a second symbol; dividing, via a dividing component, the transmission band into subcarriers; allocating, via an allocating component, the first symbol to a first subcarrier of the subcarriers; allocating, via the allocating component, the second symbol to a second subcarrier of the subcarriers; and differentially encoding, via a differential encoder, the first symbol and the second symbol.

A method of encoding a first bit and a second bit for transmission on a transmission band, the method comprising:
- mapping, via a mapping component, the first bit and the second bit into a first symbol;
- mapping, via the mapping component, the first bit and the second bit into a second symbol;
- dividing, via a dividing component, the transmission band into subcarriers;
- allocating, via an allocating component, the first symbol to a first subcarrier of the subcarriers;
- allocating, via the allocating component, the second symbol to a second subcarrier of the subcarriers;
- and
- differentially encoding, via a differential encoder, the first symbol and the second symbol.
A system for encoding a first bit and a second bit for transmission on a transmission band, the system comprising:
- a mapping component operable to map the first bit and the second bit into a first symbol, and to map the first bit and the second bit into a second symbol;
- a dividing component operable to divide the transmission band into subcarriers;
- an allocating component operable to allocate the first symbol to a first subcarrier of the subcarriers and to allocate the second symbol to a second subcarrier of the subcarriers;
- and
- a differential encoder operable to differentially encode the first symbol and the second symbol by generating a first differential symbol based on a difference between the first symbol and a pilot symbol, and by generating a second differential symbol based on a difference between the second symbol and the first differential symbol.
