Abstract
An apparatus and a method for transmitting and receiving a signal in a communication system are provided. The method includes checking a type of the signal to be transmitted; determining a number of puncture bits according to the type of the signal; and puncturing an encoded signal to be transmitted according to the number of puncture bits.
Claims10
A method for operating a receive device, the method comprising:
- receiving, from a transmit device, by a transceiver, a signal generated based on remaining bits of parity bits after puncturing, wherein the parity bits are generated by adding at least one shortened bit to bits comprising information bits to generate input bits for an encoding, if a number of the information bits is less than a number of the input bits for the encoding, and applying the encoding to the input bits;
- determining, by a hardware processor, a number of puncture bits for the parity bits;
- generating, by the hardware processor, an output signal by adding at least one bit corresponding to the number of the puncture bits to the signal;
- and
- decoding, by the hardware processor, the output signal,
- wherein the number of puncture bits is determined by adjusting a number of temporary puncture bits based on a modulation order of the signal,
- wherein the number of temporary puncture bits is determined by using a first parameter and a second parameter,
- wherein the first parameter and the second parameter are determined based on a type of the signal, the type of the signal corresponding to a protection level of the signal,
- wherein the first parameter is related to a ratio of a number of bits to be punctured to a number of bits to be shortened, and is multiplied by a number of the at least one shortened bit to generate a multiplication result, and
- wherein the second parameter is related to an integer that is added to the multiplication result to determine the number of temporary puncture bits.
