摘要： A decoding apparatus includes a memory and a receiving unit and is adapted to decode data in units of codewords each including a parity part. The memory has a storage capacity capable of storing at least data with a length equal to the length of one codeword. The receiving unit receives, as received values, elements of a codeword in a bit-interleaved form, performs bit deinterleaving and parity permutating on the received values, and stores the resultant received values in the memory.

摘要： An encoding device in a data transmission/reception system includes a first convolutional encoder that encodes an outer code, an interleaver that permutes input data, a second convolutional encoder that encodes an inner code, and a muti-level modulation mapping circuit that performs signal-point mapping based on eight-phase shift keying. When the encoding device uses the second convolutional encoder having two or more memories, the first convolutional encoder uses, as the outer code, a code with a minimum output distance greater than the maximum input distance at which the minimum-distance inner code is generated.

摘要： The present technology relates to a signal processing device, a signal processing method, and a program capable of appropriately demodulating a desired signal from a multiplexed signal obtained by multiplexing a plurality of signals. A preamble signal is detected from a multiplexed signal obtained by multiplexing a plurality of signals. When information for discriminating each of the signals that is contained in the preamble signal indicates a first signal, demodulation by a demodulator is continued and the first signal is demodulated. When information for discriminating each of the signals that is contained in the preamble signal indicates a second signal, demodulation is not performed by stopping the demodulation by the demodulator. The present technology can be applied to a signal processing device that processes signals for digital broadcasting.

摘要： The present technology relates to a reception device, a reception method, and a program therefor that enable improvement in reception performance when information on a frequency band in which no data is transmitted is known. The reception device receives a broadcast wave of an OFDM signal transmitted from a transmission device at a broadcast station that is not shown. A transmission parameter interpretation unit acquires band information indicating a “no signal” band contained in transmitted control information. An interference rejection filter unit performs filtering at least when a signal with a level higher than a predetermined level is detected on the basis of the band information from the transmission parameter interpretation unit. The disclosed technology can be applied to a reception device that receives OFDM signals, for example.
