A base station sync code transmission device comprises a primary sync code transmitter and a secondary sync code transmitter. The primary sync code transmitter is for generating and then transmitting a primary sync code at a first location in a transmission frame. The primary sync code is for acquiring synchronization at a starting point of a frame and the frame is equal to one period of a spreading code. The secondary sync code transmitter is for generating and then transmitting a secondary sync code at a second location in a frame.

    摘要: A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller controls power of the first channel signal and a second gain controller controls power of the second channel signal. An adder adds the first channel signal to the second channel signal, and a spreader spreads a signal output from the adder with a pseudo-random noise (PN) code. The base station transmits a response request message to a mobile station via the second channel, and retransmits the response request message after increasing a transmission power of the second channel when a response message is not received from the mobile station.

    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: A traffic channel transmission device for a CDMA communication system using a plurality of coding rates and orthogonal codes, determines a present channel condition and adaptively selects a coding rate and an orthogonal code according to the determination. In the device, a channel receiver receives a channel signal and a controller analyzes the received signal to decide an environment of a channel in service and generates a coding rate select signal and orthogonal code information according to the decision result. A channel transmitter includes a channel encoder for encoding transmission data at a coding rate selected according to the coding rate select signal and an orthogonal modulator for generating an orthogonal code according to the orthogonal code information to spread the encoded data with the generated orthogonal code, whereby the channel transmitter adaptively encodes and spreads the transmission data according to the channel environment. The orthogonal code information includes a number and a length of the orthogonal code.
