Abstract
A method of encoding a first bit and a second bit for transmission on a transmission band is provided. The method includes receiving a bit stream that includes the first and second bits, mapping the first bit into a first symbol, mapping the second bit into a second symbol, differentially encoding at least the first symbol and the second symbol, and causing the first and second symbols to be transmitted on a transmission band as part of a symbol stream.
Claims15
An method comprising:
- receiving the bit stream;
- mapping a first bit of the bit stream into a first symbol;
- mapping a second bit of the bit stream into a second symbol;
- differentially encoding at least the first symbol and the second symbol;
- and
- causing the first and second symbols to be transmitted on a transmission band as part of a symbol stream.
The method of claim of 1, wherein the first symbol includes the first bit, the second bit, and at least one additional bit of the bit stream, and the second symbol includes the first bit, the second bit, and the at least one additional bit.
The method of claim of 1, wherein the first symbol includes the first bit, the second bit, and a third bit of the bit stream, and the second symbol includes the first bit, the second bit, and a fourth bit of the bit stream that differs from the third bit.
A system comprising:
- a processor;
- a receiver to receive a bit stream including a plurality of bits;
- a transmitter;
- and
- a memory to store instructions that, when executed by the processor:
- cause a first bit of the bit stream to be mapped into a first symbol;
- cause a second bit of the bit stream to be mapped into a second symbol;
- differentially encode the first symbol and the second symbol;
- and.
- causing the first and second symbols to be transmitted as part of a symbol stream via the transmitter on a transmission band.
