Abstract
In one aspect, a wireless system includes an encoder configured to encode data using a spinal code which uses a function over the message bits to directly produce a sequence of constellation symbols for transmission. The wireless system also includes a decoder configured to decode the spinal code. The function may be at least one of a non-linear function and a hash function.
Claims13
1-13. (canceled)
A method to decode comprising:
- mapping a signal from an encoder to points on an I-Q plane;
- and
- decoding the points on the I-Q plane.
17-20. (canceled)
A decoder comprising:
- a non-transitory machine-readable medium that stores executable instructions, the instructions causing a machine to:
- map signals from an encoder to points on an I-Q plane;
- and
- decode a sequence of points.
1 more element
A method to provide feedback in a wireless system comprising:
- obtaining packets;
- dividing a packet of N bits into multiple code blocks;
- including a cyclic redundancy check (CRC) for each code block;
- encoding the code block in a rateless manner;
- determining how many passes and puncturing to send;
- and
- transmitting encoded symbols to a receiver.
4 more elements
A wireless system comprising:
- a transmitter comprising a non-transitory machine-readable medium that stores a first set executable instructions, the first set of instructions causing a machine to:
- obtain packets;
- divide a packet of N bits into multiple code blocks;
- include a cyclic redundancy check (CRC) for each code block;
- encode the code block in a rateless manner;
- determine how many passes and puncturing to send;
- and
- transmit encoded symbols to a receiver.
