    摘要: An A/D conversion section performs oversampling on an analog signal at a rate M times a symbol rate to convert the analog signal into a digital signal. A FIR filtering section has two delay-element sequences, each with a plurality of delay elements. The two delay-element sequences have different delay directions, i.e., a forward direction and a reverse direction. The delay directions can be switched, and according to a finite impulse response train having such delay-element sequences, a convolutional calculation is performed. A phase determining section determines a phase used in making a decision in a decision section. The decision section makes a decision on a filtered signal using the phase determined in the phase determining section to generate bit data. A digital signal receiving apparatus is thus achieved which determines a phase with a high accuracy without increasing the oversampling number, and performs a fast calculation while having a reduced circuitry scale.

    摘要: A relay apparatus, terminal apparatus and relay method for relaying signals with a reduced scale of the apparatus, without temporally switching between transmission and reception and with reduced waste of time when relay is performed at the same frequency on a radio communication network on which bidirectional communication is performed. A radio reception section 202 outputs information signals to a switch 208, outputs relay control signals to a demodulation section 204 after subjecting predetermined radio reception processing. The demodulation section 204 demodulates a relay control signal. A relay control signal processing section 206 decides the possibility of relay of information signals and inquires, when the relay is possible, whether the terminal apparatus on the receiving side can receive this information signal or not. Furthermore, the relay control signal processing section 206 connects a switch 208 during the stored relay time. The switch 208 is connected only the information signals to be relayed are received under the control of a relay control section 2063.
