An object of the present invention is to enable appropriate switching among a plurality of modes including a cellular communication mode and an RFID information receiving function. A communication system is comprised of an RFID configured to transmit predetermined ID information of its own, a server capable of being connected to a cellular communication network, and an aggregation point for aggregating information from the RFID. In the communication system, the aggregation point, which is comprised of a mobile communication terminal or the like, is provided with an ID receiver for receiving ID information from an RFID, and a cellular communication part for performing cellular communication via the cellular communication network. Furthermore, the aggregation point is provided with a new mode controller for receiving a switching signal for switching among a plurality of modes including the cellular communication mode and the RFID information receiving function from the server, and for performing a mode switching control based on the received switching signal.

A diversity receiving system for differential detection of minimum shift key (MSK) signals. The system may be advantageously implemented in order to realize high quality mobile satellite communication systems where shadowing is a significant problem and channel bandwidth and power are constrained. Signals from each of a plurality of receiving branches are translated to different intermediate frequencies which differ from each other by multiples of the transmitted signal symbol rate. The intermediate frequency signals are summed and detected via a common differential detector, the latter being followed by a low pass filter having a bandwidth corresponding to a fraction of the symbol rate. The plural signals are easily and stabely combined at an intermediate frequency stage without phase adjusters, signal quality measurement circuits or switching controllers. Moreover, the error rate performance is equivalent to that of post detection equal gain combining diversity schemes, which require plural complete receiving systems.
