摘要:
In a mobile communication system in which a TDMA system and a time-divided CDMA system are commonly used, a high-speed TDMA data transmission system is introduced, and down-links, from base stations (1 to 3) to mobile stations (31 to 34, 41, 42, 51 and 52) and up-links, from mobile stations to base stations, comprise different communication capacities from each other and a couple of a down-link and an up-link having different communication capacities are handled as one communication channel (asymmetric channel). A mobile communication system which is to transmit a large quantity of high-speed data and is able to correspond to multimedia circumstances may be realized by assigning the above-mentioned asymmetric channel to the mobile communication system.

In cases where a radio communication is performed between a ground radio base station and a subscriber station, when a delay time J passes after the transmission of a radio wave from the ground radio base station to a stratospheric platform base station, another radio wave relating to the same information as that indicated by the radio wave is transmitted from the ground radio base station to the subscriber station. Therefore, in the subscriber station, a phase of the radio wave directly transmitted from the ground radio base station is synchronized with a phase of the radio wave transmitted from the ground radio base station through the stratospheric platform base station. Accordingly, the subscriber station can change over from one radio wave, of which the strength is weakened, to another radio wave.

After amplification of a predetermined frequency component f0+nfd of an intermediate frequency signal extracted by a mixer (44), a shared wave signal thereof is demodulated and modulated, thereby reproducing TDMA serving as a shared wave signal. Further, a subtracter (51) subtracts the TDMA serving as the shared wave signal from the intermediate frequency signal to extract CDMA#1 signal serving as a desired wave signal.
摘要:
To provide a connector housing in which the locking between an elastic lock piece and a terminal can be released without contacting a release tool with the terminal and a terminal retaining portion. A connector housing has a terminal insertion hole whose front end is in communication with a connection opening for connecting a mating terminal whereas a rear end of the terminal insertion hole is in communication with a terminal insertion opening. An elastic lock piece is provided within the terminal insertion hole in such a manner that a flexure-allowing space is formed at one side portion of the terminal insertion hole, the elastic lock piece having a terminal engagement portion for engagement with an inserted terminal. A release-purpose retaining portion for being engaged with a release tool so as to flex the elastic lock piece in a lock-releasing direction is formed on and projects from that surface of the elastic lock piece facing the flexure-allowing space.
