摘要： An object is to generate a pilot signal for estimating transmission characteristic of a transmission channel which is suitable for the OFDM/OQAM multicarrier modulation. A phase reference pilot symbol of which a modulation amplitude is suppressed to zero, and an amplitude reference pilot signal obtained through modulation performed by using an amplitude known to a reception end are transmitted from a transmission end, and the transmission characteristic of the transmission channel is estimated and compensated by using the phase reference pilot signal and the amplitude reference pilot signal at the reception end. Thus, it is possible to simplify frame generation process performed at the transmission end, and reduce transmission power for the phase reference pilot signal.

摘要： A transmission method of a digital broadcast which is compatible with the DVB-T terrestrial digital broadcast system in Europe and saves a battery in a mobile terminal is provided. Superframes in DVB-T are divided into units each including plural symbols so that an integer number of TS packets can be carried in each slot. At least one slot is used to transmit one service. Energy dispersion, Reed-Solomon coding, byte interleaving, convolutional coding, and time interleaving are applied to each service. When services for mobile terminal reception and services for fixed terminals are transmitted as the provided services, null packets may be transmitted before and after the slot carrying the mobile receiver service so that the fixed reception service and the mobile reception services are not mixed. If the fixed terminal handles TS packets of the mobile reception service as error packets, it could have no problem in reception.

摘要： In an OFDM transmission scheme, in order to compensate any frequency response variations time wise resulted from any distortion in a transmission path, out-of-synchronization with passage of time, frequency drift, and phase shift, and to improve a demodulation characteristic, a PS detector in a receiver receiving an OFDM signal detects a pilot symbol. A PS1 TPFR calculator calculates a frequency response of the transmission path for a first pilot symbol, while a PS2 TPFR calculators calculates a frequency response of the transmission path for a second pilot symbol for a second pilot symbol. Thereafter, a compensation vector calculator calculates compensation vectors from the frequency responses of the transmission path for both of the first and second pilot symbols by linear approximation. A frequency response compensatory compensates the frequency response variation of subcarriers in a data symbol based on the calculated compensation vectors.

摘要： A plasma display device disclosed herein is capable of enhancing the contrast of external light, facilitating application of phosphor paste on the bottom of each space surrounded by lattice-like barrier ribs, and reducing a variation in the amount of the phosphor paste applied as much as possible. The lattice-like barrier ribs include lateral ribs extending along a first direction while being nearly in parallel to each other, and vertical ribs extending along a second direction different from the first direction while being nearly in parallel to each other. Each of the lateral ribs is composed of two or more rows of rib elements. Notches for communicating spaces surrounded by the vertical ribs and the lateral ribs to each other in the first direction and/or the second direction are formed at least in portions of the vertical ribs and/or the lateral ribs.
