摘要： An apparatus and method for determining an optimum modulation scheme and code rate in a communication system using a variable transmission scheme. In a transmitter included in the communication system, an encoder encodes an encoder packet (EP) and a plurality of modulators having different modulation orders modulate sub-packets being codewords output from the encoder. A selector selects one of the modulators by comparing an MPR (Modulation order Product code Rate) being a ratio of an EP size to a number of payload modulation symbols, and comparing the MPR with a threshold.

摘要： A broadcasting receiving apparatus and method in a broadcasting system are provided. In a broadcasting receiver, a demodulator demodulates a received broadcasting signal, clips a soft metric value for the demodulated signal to a number of bits, and outputs the clipped soft metric value. A mapper maps the clipped soft metric value to an index value with a resolution inversely proportional to the quantization level of the soft metric value. A deinterleaver deinterleaves the index value and a demapper demaps the deinterleaved index value to a representative value being a soft metric value from a range of soft metric values mapped to the index value. A channel decoder decodes the representative value.
