Provided are a program, a method, and an apparatus for decoding coded data, capable of completely restoring an original stream when decoded data is coded again by causing a computer to function as: means for receiving an input of a signal coded by lossy compression and orthogonally projecting an optional real number vector on one convex aggregate X in a first vector space in which the decoded signal is present; means for judging convergence of convex projection and obtaining a real number vector x belonging to the aggregate X to output the same as a decoded signal when the convergence of the convex projection is judged; and means for orthogonally projecting an optional vector of the first vector space on one convex aggregate Y in a second vector space different from the first vector space when the convergence of the convex projection is not judged, and then repeating orthogonal projection on the aggregate X and the aggregate Y with the coded signal set as an initial value.

Provided is a frame configuration usable for both SISO transmission and MISO and/or MIMO transmission. A frame configurator of a transmission device configures a frame by gathering data for SISO and configures a frame by gathering data for MISO and/or MIMO data, thereby to improve the reception performance (detection performance) of a reception device.

In order to implement both a physical later pipe (PLP) structure and a plurality of receiver classes, a transmitting apparatus includes: a signaling information generation unit which generates signaling information including a transmission parameter for each of PLPs; a PLP processing group which performs processing based on the transmission parameter for each of the PLPs; and a transmitting unit which transmits data including the generated signaling information and PLP data for each of the PLPs. The PLP data is received by a receiving apparatus that is indicated by a flag of the PLP and is not received by another receiving apparatus, the receiving apparatuses being included in a plurality of receiving apparatuses classified under a plurality of states. The generated signaling information includes, as the transmission parameter for each of the PLPs, the flag of the PLP.
摘要:
An OFDM transmitter and an OFDM receiver respectively transmit and receive N (N≧2, N is an integer) control symbols. For each control symbol, a guard interval time-domain signal is, for example, identical to a signal obtained by frequency-shifting at least a portion of a useful symbol time-domain signal by an amount different from any other symbol, or to a signal obtained by frequency-shifting one or both of a portion and a span of a useful symbol interval time-domain signal different from any other symbol by a predetermined amount.
摘要:
A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation scheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.
