摘要： An antenna diversity communications device switches communications paths between a plurality of antennas to improve reception in a frequency diversity communications system. Antenna selection is done in response to measurement of the receiving condition of the selected antenna. A memory unit stores frequency difference information between the current channel and the next channel. When the frequency difference between the current channel and the next channel is small enough to predict good correlation between the channels, and if current receiving conditions are good, the current channel remains connected. When the frequency difference between the current channel and the next channel is large enough to predict poor correlation, or if the receiving conditions on the current channel are bad, one of the other channels is selected.

摘要： A highly reliable and high-speed data transmission is made by using an FH or MFSK mode as suitably selected according to the usage of channels. When a reception signal is entered into a receiver through a transmission line, (i) a signal processing unit supplies the spectrum intensity values of carrier frequencies, (ii) a channel detection unit controls the phase of a time slot based on the spectrum intensity values, selects the MFSK or FH modulation mode, and supplies reception code data corresponding to detected carrier frequencies, and (iii) a decoder supplies reception information data based on the reception code data. When transmission information data are entered into a transmitter, (i) a coding unit supplies, according to the selected modulation mode, transmission code data based on the transmission information data, (ii) a channel generation unit supplies, based on the transmission code data, carrier frequencies to be used and (iii) a waveform generation unit supplies a transmission signal to a transmission line.

摘要： To use high noise transmission lines, such as an electric wire, as the lines to transmit signals, it is imperative to reduce the level of signals. The present invention is provided with a sending signal generating means 10, which outputs converted data after converting an input signal into a plurality of carrier signals assuming values at such intervals on the axis of frequency that the frequencies may not interfere with each other. If an interfering noise with any one of the plurality of frequencies arises on the transmission line, removal of only a carrier of the noise frequency would leave the communication in a good condition. Furthermore, better results can be hoped for if the respective carrier signals are so arranged as not to interfere with each other or so arranged to intersect orthogonally with each other not only on the axis of frequency but also on the axis of time

摘要： A packet-relay unit 100 including a first interface unit (110), a second interface unit (120), and a function-setting switch (130). The second interface unit (120) includes a classifying unit (121), a priority control unit (122), and a transceiving unit (123). When the function-setting switch (130) sets a “QoS function” as “operative”, the classifying unit (121) transfers packets transferred from the first interface unit (110) to the priority control unit (122). The priority control unit (122) provides priority control over the transferred packets such that the transferred packets are preferentially treated at a wireless zone connected to the second interface unit (120), whereby the priority-controlled packets are transferred to a transceiving unit (123) from the priority control unit (122). When the function-setting switch (130) sets “the QoS function” as “inoperative”, the classifying unit (121) transfers the transferred packets directly to the transceiving unit (123).

摘要： An amplifier circuit for amplifying a change in a resistance value of a magnetic resistance element is formed by connecting a first and a second current mirror circuits having the same structure in cascode, so that a voltage change is amplified without using a capacitive coupling. Hence, a high-pass filter is not created as a parasitic circuit, whereby a gain is maintained high in the low frequency region and a low frequency characteristic is excellent. Further, since control electrodes of transistors which form each current mirror circuit are grounded through the capacitance, a noise is reduced without using a conventional feedback circuit. This eliminates an influence of the feedback circuit over a high frequency characteristic, and therefore, a high frequency characteristic becomes excellent.

摘要： A packet shaper includes: a TCP packet queue for storing TCP packets; a UDP packet queue for storing UDP packets; a scheduler for outputting a packet from one of the queues into a rate-setting control unit. Control based on a total queue length is performed to deterioration of image quality or tone quality in the audio/visual communications according to a connection-oriented protocol like TCP.
