Title: Multichannel access control system
Inventor: KONDO HARUO
IPC: H04W84/08
Filed: 1993-02-16
Abstract: PURPOSE:To prevent the deterioration of throughput due to the retransmission by requesting retransmission the only signal for which synchronizing words are unable to be detected at a base station again from among signals sent by plural access channels from a mobile station. CONSTITUTION:Beam reception sections 39a-39c at the base station measure the reception level of signals sent from the mobile station and detect the synchronizing words. A control section 12 prepares retransmission request information including beam numbers, access channel numbers, and slot numbers for the arranged beam of the access channel which detects the signal level but can not detect the synchronizing words. Multiplexers 41a-41c comprise burst signals and beam transmitters 40a-40c send to respective beams. The mobile station sends a signal again based on the multi-channel collision eliminating algorithm when the content of the retransmission request signal coincides with the stored content of transmission. Thus, the deterioration of throughput due to the retransmission can be prevented without increasing the invalid traffic.

Title: Distortion compensation circuit
Inventor: FUKUGAHARA TSUTOMU
IPC: H04B1/04
Filed: 1985-02-14
Abstract: PURPOSE:To cancel automatically deterioration of the characteristic of a device by measuring automatically a harmonic distortion of a pilot signal and using a differential amplifier so as to compensate a harmonic distortion generated between a transmitter and a receiver depending on the quantity of the distortion. CONSTITUTION:A transmission signal superimposed with a pilot signal is sent from the sending side. A differential amplifier 7 of a distortion compensating circuit 6 amplifies an output signal of a receiver 5, the distortion of the output is extracted by BPF 8 and a detector 9 converts it into a DC component. A comparator 10 controls an FET 11 when the DC component of the output of the detector 9 is larger than a reference voltage Vref. The FET11 acts like a variable resistive element and changes the value of the variable resistive element 11 in proportion to the degree that the said DC component is larger than the voltage Vref. As a result, an FET 13 acts like a distortion generating circuit to generate the distortion component. The component is fed to the differential amplifier 7 in opposite phase to the reception signal and the adjusted component is reduced.

Title: Power amplifier
Inventor: IDA MASARU
IPC: H03F1/02
Filed: 1982-02-24
Abstract: PURPOSE:To prevent the generation of spike noise at power supply switching, by avoiding a transistor (TR) for switching from being non-conductive in the switching of power supply voltage in response to the amplitude of input signal. CONSTITUTION:When an input signal amplitude is small, a diode 8a is inversely biased to be non-conductive, and a TR1a performs amplification by using a power supply voltage +V1. since a TR7a amplifies the input signal and supplies the output to a load 3 via a by-pass circuit 14a, then the TRs 1a, 7a perform amplification in parallel. When the signal amplitude is large, the diode 8a is conductive and a diode 5a is inversely biased, then the power supply voltage in response to the amplitude of the input signal is applied to the TR1a from the TR7a via the diode 8a. Thus, since the TR7a is not non-conductive through the switching, no spike noise is generated. This applies also to the negative power supply side.
