Abstract
A system and method for preserving neighborhoods in codes are provided. A method for transmitting information includes receiving an information string to transmit, generating a first address and a second address from the information string, encoding the first address and the second address with a layered code encoder, thereby producing a codeword and transmitting the codeword. The generating is based on a linear block code.
Claims26
A method for transmitting information, the method comprising:
- receiving an information string to transmit;
- generating a first address and a second address from the information string using a linear operation;
- encoding the first address and the second address using a layered code encoder to produce a codeword from both the first and second addresses;
- and
- transmitting the codeword.
2 more elements
A method for receiver operation, the method comprising:
- receiving an information vector from a transmission by a transmitter;
- decoding a first address and a second address from the information vector using a layered code decoder;
- and
- generating an information string from both the first address and the second address using a linear operation.
1 more element
A transmitter comprising:
- a channel encoder configured to generate an output codeword from an information vector provided by an information input, wherein the information vector is encoded by a layered neighborhood preserving code having most significant bits (MSBs) indicating a neighborhood in a code space, and having least significant bits (LSBs) indicating a location in the neighborhood;
- and
- a modulator/transmitter circuit coupled to the channel encoder, the modulator/transmitter circuit configured to prepare the output codeword for transmission over a physical channel.
A communication module comprising:
- an address generator configured to generate a first address and a second address from an information string using a linear operation;
- a layered code encoder configured to encode both the first address and the second address to produce a codeword;
- and
- a transmitter configured to transmit the codeword.
