Abstract
Blind detection of code rates for codes with incremental shortening involves determining a decoding code rate for decoding words that are based on codewords of a code that exhibits incremental shortening over a range of code rates. Incremental shortening is a code structure or coding property according to which different numbers of bits in encoding blocks that are to be encoded are set or frozen to a fixed value, to provide the range of code rates. This property enables blind detection of a decoding code rate, without explicit signaling or prior configuration of code rates between a transmitter and a receiver.
Claims27
A method comprising:
- receiving, by a wireless receiving device, a word that is based on a codeword of a code having an incremental shortening property over a range of code rates;
- performing, by the wireless receiving device, a blind detection of a code rate within the range of code rates;
- and
- decoding, by the wireless receiving device, the received word using the blindly detected code rate.
A non-transitory processor-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method comprising:
- receiving a word that is based on a codeword of a code having an incremental shortening property over a range of code rates;
- performing a blind detection of a code rate within the range of code rates, to be used in decoding the received word;
- and
- decoding the received word using the blindly detected code rate.
An apparatus comprising:
- a wireless receiver configured to receive a word that is based on a codeword of a code having an incremental shortening property over a range of code rates;
- and
- a decoder, operatively coupled to the wireless receiver, configured to:
- perform a blind detection of a code rate within the range of code rates;
- and
- decode the received word using the blindly detected code rate.
