摘要： Disclosed is a wireless communication device that, when both localized transmission and distributed transmission are used, can obtain channel estimation accuracy equivalent to that of localized transmission with distributed transmission. With this device, a setting unit (108) sets the power density of a reference signal by setting the arrangement density in the time domain of the reference signal according to the continuity in the frequency domain of the reference signal. In addition, the setting unit (108) increases the arrangement density in the time domain of the reference signal as the continuity decreases. A transmission RF unit (111) transmits a reference signal having the power density that has been set by the setting unit (108).

摘要： A video signal processor for preventing image damage resulting from when a first signal and a second signal are converted into each other. When a first signal (an interlaced scanning format signal) is inputted, according to a mode discriminating signal from a mode discriminator, a mixer/selector receives the motion detecting signal from the mode discriminator, adaptively mixes both outputs of a delay circuit and a line interpolating filter (IPF) and uses the combined outputs as an interpolation signal. When a second signal (a progressive scanning format signal converted to an interlaced scanning format signal) is inputted, the mixer/selector selects either the output of the second signal or the output of a delay circuit according to the mode discriminating signal and the field indexes from the mode discriminator and makes it as an interpolation signal. When an input signal is converted from a first signal to a second signal, the mixer/selector receives the motion detecting signal from the mode discriminator and selects the output from the line interpolating filter as an interpolation signal (intra-field interpolation) for at least one field of the changed-over signal according to the mode discriminating signal from the mode discriminator.

摘要： This invention relates to a transmitter apparatus, a receiver apparatus, a transmission method and a notification method that, when a switching between MIMO communication and non-MIMO communication is performed, can suppress the increase of an SRS (Sounding Reference Signal) resource, while suppressing the degradation of trackability of temporal variation of a channel. In a terminal (200), a mapping unit (212) maps an SRS sequence, which is received from a pilot, generating unit (216), on the basis of information related to an SRS hopping pattern, received from a base station (100). For this SRS hopping pattern, the frequency of the SRS transmissions via a first one of a plurality of antennas of the terminal (200) is higher than that of the SRS transmissions via a second one of the plurality of antennas of the terminal (200).
