摘要： The universal platform for the SDR of the present invention employs the direct conversion approach with the n-port MMIC followed by reconfigurable reprogrammable devices such as DSP's or FPGA's. The universal platform is based on the linear operation of the devices. Thus, the DC offset problem may be solved. It is also possible to support very wide bandwidths compared with conventional I/Q receivers. Therefore, the present universal platform is suitable for multimode and multiband communications.

摘要： A data processing device and a data processing method that can readily process control data having its PAPR improved. In a transmission device, a padder pads control data necessary for demodulation with zeros as dummy data, and a scrambler scrambles the padded control data (post-padding control data). A replacement unit replaces scrambled dummy data in the scrambled post-padding control data with the dummy data, and a BCH encoder and an LDPC encoder perform BCH encoding and LDPC encoding as error correction encoding on the replacement data obtained through the replacement. A shortening unit performs shortening by deleting the dummy data contained in the LDPC code and puncturing the parity bits of the LDPC code. The device can be applied in cases where control data is subjected to error correction encoding and is then transmitted, for example.

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.
