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.

摘要： Provided is a method and apparatus for decoding a Multi-Protocol Encapsulation Forward Error Correction (MPE-FEC) frame in a Digital Video Broadcasting-Handheld (DVB-H) system. Packet Identifier (PID) filtering is performed on a Transport Stream (TS) packet received via a wireless network to detect a TS packet, and a table ID is detected from header information of the section data to identify the section data type. If the section data is an MPE section, frame buffering is performed. If there is a remaining portion in the data region after storage of an IP datagram of the last MPE section, zero-padding is performed on the remaining portion. If the section data is an MPE-FEC section, frame buffering is performed on parity data extracted from the MPE-FEC section.

摘要： An apparatus and method are provided for receiving data generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping in a wireless communication system. A fast Fourier transform (FFT) processor receives in-phase/quadrature phase (I/Q) data of a radio channel generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping, and performs an FFT process for the I/Q data. A symbol deinterleaver performs a process for symbol deinterleaving the FFT I/Q data and reference values to be used for symbol demapping of the I/Q data and outputs the symbol-deinterleaved I/Q data and reference values. A symbol demapper performs a process for symbol demapping the symbol-deinterleaved I/Q data according to the reference values. A bit deinterleaver performs a process for bit deinterleaving the symbol-demapped data. A demultiplexer demultiplexes the bit-deinterleaved data.
