摘要： When switching to a path whose directivity changes greatly or a path with a widely different propagation delay, transmission is performed for both directivities for a certain period of time. Then, transmission is performed for one directivity. When the switching of transmission directivities is controlled, this allows correct reception of signals and prevents instantaneous interruption due to loss of synchronism even if transmission is performed by switching to a path with a widely different propagation delay.

摘要： A compensator eliminates frequency offset contained in digital-converted signals output from A/D converters. A weighting coefficient calculator, a complex multiplier and an adder eliminate an interference component from a signal from which frequency offset is eliminated. A differential coherent detector demodulates a signal from which the interference component is eliminated. A decoder decodes the demodulated signal, while a frequency offset estimator estimates frequency offset using the demodulated signal and a known symbol.

摘要： A complex multiplying section multiplies a receiving signal by a complex weighting factor of a weighting factor controlling section. The output is added by an adding circuit, and decoded by a decoding circuit so as to obtain a received signal. The weighting factor of the weighting factor controlling section is set using only the weighting factor calculated by a synchronous burst having a different unique word pattern. On one hand, it is assumed that an interference station having the same unique word pattern exists. Then, a decision feedback adaptive array antenna receiving circuit 400, which does not update the weighting factor using the unique word pattern, performs a signal reception. On the other hand, it is assumed that no interference station having the same unique word pattern exists. Then, the conventional decision feedback adaptive array antenna receiving circuit 500, which updates the weighting factor using the unique word pattern, performs a signal reception. Thereafter, a correct signal is selected from either one of the circuits. Thereby, the complex weighting factor of the adaptive array antenna is appropriately updated, so that a received signal can be extracted from the desired signal.

摘要： Liquid to be injected from an injection nozzle is supplied through a liquid supply channel toward the injection nozzle. Negative pressure for sucking the liquid injected from the injection nozzle through a suction port is produced by a suction unit and guided through a suction channel toward the suction port. A bypass channel which bypasses the liquid supply channel on the upstream side with respect to the injection nozzle and connects with the suction channel is provided. The bypass channel is opened and closed by an opening and closing unit. According to this structure, flow of unnecessary liquid from the injection nozzle can be reduced by opening the opening and closing unit while injection of liquid is stopping.
