If it is judged by a signal from a first signal processing unit that a signal of a first communication system is not received and it is judged by a signal from a second signal processing unit that a signal of a second communication system is received, wireless communication is performed by the second communication system. If it is judged that the signals of the first and the second communication systems are received, a system judging unit judges which communication system is to be used for the wireless communication, based on the signals from the first signal processing unit and the second signal processing unit. If the wireless communication is to be performed by the first communication system, diversity reception or transmission is performed by first and second antenna elements.
摘要:
A modulation apparatus which can be applied to the conventional analog PLL modulation system without using an enormous reference table, enables a phase distortion to be compensated accurately without requiring timing control with high accuracy, and can be applied to communication systems that do not perform amplitude modulation. In this apparatus, a signal generation section (101) generates a baseband phase signal. A phase distortion compensation section (102) obtains a phase distortion by multiplying a magnitude of a frequency change at predetermined time or magnitude of phase change between adjacent data of the baseband phase signal by a parameter specific to the apparatus, and thereby compensates the baseband phase signal for the phase distortion. A storage section (103) stores the parameter and calculation equation. A modulation section (105) modulates a frequency converted signal input from a frequency conversion section (104) using the baseband phase signal to generate a modulated signal.

There is described an image forming system constituted by an image forming apparatus and an external apparatus. The image forming apparatus includes a storing section to store image data, an image forming section and a controlling section to control the image forming operations. While, the external apparatus includes a data generating section to generate a plurality of print data sets, which are different from each other with respect to at least a part of each print data set, a selecting section to select selected-image data from the image data and a transmitting section to transmit the plurality of print data sets and selecting information indicating the selected-image data to the image forming apparatus. Based on the selecting information, the controlling section controls the image forming section so as to couple the selected-image data with each of print data sets to output coupled-image data.

A radio communication system includes a base station of a radio communication system A, a base station of a radio communication system B operation in non-synchronized way with the base station, and a mobile station capable of communicating with both of the radio communication system A and the radio communication system B. The base station includes a radio unit for transmitting/receiving a radio wave to/from the mobile station and a system information estimation unit for estimating the system information on the radio communication system B and outputting the system estimation information. The radio unit of the base station reports the system estimation information on the base station to the mobile station. The mobile station receives the system estimation information on the base station in advance so as to perform effective switching without using a cabled connection from the radio communication system A to the radio communication system B via a relay device or the like.

On the surface of the first principal plane, a first region made up of the p-type Ga N compound semiconductor including at least Ni is formed. On the surface of the first region, an electrode composed of an alloy including Ni and Aluminum is formed. On the electrode, a pad electrode for external connection consisting of Al or Au is formed.
摘要:
A gateway apparatus on a receiving side, which controls a receiver terminal, sends a tunnel connection request message to a gateway apparatus on a sending side that controls a sender terminal where multicast packet broadcasting originate. In contrast, the gateway apparatus on the sending side that has received the tunnel connection request message establishes a virtual communication path for transferring a multicast packet to the gateway apparatus on the receiving side.
