Abstract: A terminal apparatus receives data of a program to be viewed selected from among broadcast programs, and notifies viewing information indicating the program to be viewed. A base station apparatus broadcasts the data of the program to a cell, mutually notifies the broadcast program between cells, acquires the viewing information from a terminal apparatus, and starts to broadcast the program in the destination cell when predicting that the terminal apparatus is moving into the cell where the program that is being viewed is not broadcast.

Abstract: An electronic mail system comprises a transmitting terminal which transmits an electronic mail, a server which receives the electronic mail from the transmitting terminal, retrieves a specific data relating to the electronic mail from at least one of a network coupled to the sever and an internal memory of the sever, transmits at least one of the specific data and an item list of the specific data, and transmits the electronic mail, and a receiving terminal which receives at least one of the specific data and the item list of the specific data from the server, receives the electronic mail from the server, and displays at least one of the specific data and the item of the specific data.

Abstract: An equalizer circuit includes a carrier sensor, first and second equalizer units, carrier sense controller, and reception signal switching unit. The carrier sensor senses the start of a reception signal on the basis of a signal representing the reception level of the reception signal. The first and second equalizer units equalize the reception signal. The carrier sense controller alternately enables the first and second equalizer units every frame reception in accordance with an output from the carrier sensor. The reception signal switching unit alternately switches between outputs from the first and second equalizer units every frame reception and outputs the selected output as demodulation data.

Abstract: The invention provides a radio reception apparatus by which a delay by initialization of an equalizer is minimized and an equalization process with a minimum preamble signal can be performed normally to assure a high transmission efficiency and suppress an increase of the power consumption. First and second RF sections convert the frequencies of reception data from first and second antennae. A comparison section compares reception sensitivities of outputs of the first and second RF sections to select the output having a higher reception sensitivity.

Abstract: In the present invention, UW gate signal generator generates a UW gate signal for detecting a unique word. Gate circuit masks received signal using UW gate signal. PN detector compares a preset unique word signal set value and the signal output from inverting circuit during the active-high interval of UW gate signal, detects whether or not they are matching, and outputs the result. UW detector compares a preset unique word signal set value and the signal output from gate circuit during the active-high interval of UW gate signal, and outputs UW detection signal. Error detector outputs a detection stop signal for stopping unique word detection based on the signals output from PN detector and UW detector.

Abstract: In the phase modulation multiplexing transmission unit 1, a digital input signal is divided by a signal division unit, each of the resultant division signal is output to multiplication units 3a and 3b, respectively. The multiplication units 3a and 3b multiply the division signals by spread code signals output from spread code generators 2a and 2b, respectively. A multiplication signal Sb output from the multiplication unit 3b is shifted by &pgr;/2 radian through a phase shifter 4, which is added to a multiplexing signal Sa output from the multiplication unit 3a through an adder 5. A synthetic signal Se(n) output from the adder 5 is BPSK modulated through a modulator 6, which is transmitted through a transmission amplifier 7 and an antenna 8.

First and second RF sections convert the frequencies of reception data from first and second antennae. A comparison section compares reception sensitivities of outputs of the first and second RF sections to select the output having a higher reception sensitivity. First and second carrier detection sections detect a start of reception data based on an output signal of the comparison section and causes an equalization processing section to end its demodulation upon reception of a demodulation data end signal. A first OR circuit outputs a result of logical ORing of the outputs of the first and second carrier detection sections.
