Abstract
An apparatus and method for rate dematching in a communication system are provided. The apparatus includes an input sequence generator, an error calculator, and a puncture/repetition determiner. The input sequence generator calculates if current input data among data, which are input in interleaved sequence, corresponds to any nth sequence among before-interleaved sequence. The error calculator calculates an error for the current input data using the calculated sequence. The puncture/repetition determiner determines type of the current input data using the error for the current input data.
Claims22
An apparatus for rate dematching, comprising:
- a processor for calculating rate dematching parameters for current data, the parameters including an order among a data sequence before interleaving and an error based on the calculated order;
- a selector for receiving a current data, a previous data, and an output data;
- and
- a state machine circuit for receiving the calculated rate dematching parameters and controlling the selector based on the calculated rate dematching parameters to selectively perform at least one of a puncturing process and a repetition process.
A method for rate dematching, the method comprising:
- calculating rate dematching parameters for current data, the parameters including an order among a data sequence before interleaving and an error based on the calculated order;
- and
- selectively performing at least one of a puncturing process and a repetition process based on the calculated rate dematching parameters.
