摘要： A dial pulse detector in a paging system for rendering a paging service for a subscriber who uses a mechanical telephone includes a delay correlativity calculator for receiving dial pulses generated by predetermined pre-test dialing digits dialed by the subscriber, calculating the correlativity between the delayed dial pulse and undelayed dial pulse to sample a reference signal of the dial pulse. An energy correlativity calculator calculates the energy correlativity between the sampled reference signal and the successively received dial pulse to examine the validity of the reference signal. A dial pulse verifier operates according to recognition of the validity of the reference signal by the energy correlativity calculator and checks input number of times and input time of the dial pulse so as to verify whether the dial pulse corresponds to the pre-test dialing digits.

摘要： A forward link device of a multicarrier CDMA communication system with an overlay scheme in which a multicarrier system and an IS-95 system share same frequency bands. In the forward link device, four encoders encode input data of corresponding rates with a 1/3 coding rate, respectively. A first repeater repeats two times full rate symbols output from the first encoder, and second to fourth repeaters repeat symbols output from the second to fourth encoders, respectively, according to a predetermined number of times, to match the number of corresponding output symbols to the number of full rate symbols. First to fourth interleavers interleave the symbols output from the first to fourth repeaters, respectively, to uniformly distribute the symbols of the same data bit to the carriers.

摘要： In a transmission device and method for a CDMA communication system, when a shorter frame message is generated during transmission of a longer frame message, the transmission of the longer frame message is interrupted, whereupon the shorter frame message is immediately transmitted in place of a portion of the longer frame message. In one embodiment, after the longer frame message is interrupted and the shorter frame message is transmitted, only the tail portion of the longer frame message is transmitted thereafter. That is, the replaced portion of the longer frame message is not transmitted following the shorter frame message transmission. In an alternative embodiment, following the shorter frame message transmission, the remainder of the longer frame message, from the point of interruption, is transmitted in its entirety. In the latter case, the longer frame message is delayed by the length of the shorter frame message.
摘要翻译：在用于CDMA通信系统的传输设备和方法中，当在较长帧消息的传输期间产生较短的帧消息时，较长帧消息的传输被中断，因此较短的帧消息被立即发送，代替部分的较长帧消息。在一个实施例中，在更长的帧消息被中断并且发送较短的帧消息之后，仅在其后发送较长帧消息的尾部。也就是说，更短帧消息的更换部分在更短的帧消息传输之后不被发送。在替代实施例中，在更短的帧消息传输之后，从中断点开始，更长的帧消息的其余部分被全部传输。在后一种情况下，较长帧消息被延迟较短帧消息的长度。

A base station stores a reference sync channel RTD (Round Trip Delay), calculates the difference between the reference sync channel RTD and a measured sync channel RTD, and outputs a time alignment control signal on a forward control channel when the calculated RTD error exceeds a predetermined value, during a data communication. A terminal receives the time alignment control signal on the forward control channel and time aligns a reverse traffic channel based on the received time alignment control signal.
