Description

Other transmission line communication device of wireless communication network {DATA TRANSMITTING AND RECEIVING DEVICE USING ORDER WORE IN A WIRELESS COMMUNICATION NETWORK}

The present invention relates to a short-circuit communication apparatus of a wireless communication network, and more particularly to a device that enables a short-circuit communication even when a separate transceiver for the other short-circuit communication is not provided.

In general, the order wire in a wired communication network refers to a line used for maintenance or maintenance of a communication facility separately from the call line, whereas the other wire in a wireless communication network refers to a data frame in a data frame. A data channel or a voice channel used for communication among pre-ambles of any burst. Such short-circuit communication can be said to play an important role as an emergency call means in dealing with increasing communication requirements, ensuring survivability and flexibility, and constructing a communication system capable of high-capacity high-speed processing.

According to the prior art, rudder wires have been operated in a point-to-point manner between wired devices or between wireless devices, that is, by communication means. Therefore, only the wireless devices can make a call to each other, and only wired devices can make a call to each other. In particular, the radio equipment is equipped with a separate transceiver to use the channel dedicated to other short-circuit.

Therefore, according to the related art, in order to enable other short-circuit communication in a wireless communication network, a separate channel and a transceiver must be provided. In addition, as a separate transceiver for other short-circuit communication is required, there is a disadvantage in that the volume of the entire wireless communication equipment becomes large.

Accordingly, an object of the present invention is to provide an apparatus that enables other short-circuit communication even when a separate channel for other short-circuit communication is not provided in a wireless communication network.

Another object of the present invention is to provide an apparatus for enabling other short-circuit communication even when a separate transceiver is not provided for other short-circuit communication in a wireless communication network.

Still another object of the present invention is to provide an apparatus for preventing the bulk of communication equipment from becoming bulky as other wire communication is required in a wireless communication network.

The present invention for achieving these objectives is to classify each channel with a unique Walsh code and PN code corresponding to the pilot data, traffic data, and other short-circuit data, and then add data of all channels to communicate. The present invention proposes another short-circuit communication device that outputs as a signal for the circuit.

Another short circuit communication apparatus of a wireless communication network according to the present invention comprises: a PN code generator for generating a PN code; First means for frequency-mixing pilot data with a predetermined pilot Walsh code, frequency-mixing the PN code, and then filtering and amplifying the pilot data; Second means for frequency-mixing traffic data with a predetermined traffic Walsh code, frequency-mixing the PN code, and then filtering, amplifying and outputting the traffic data; Third means for frequency-mixing the other short-circuit data with a predetermined other short-line Walsh code, mixing the PN code with the frequency, filtering, amplifying and outputting the mixed-line data; First adding means for adding and outputting the output of said second means and the output of said third means; And a second adding means for adding the output of the first adding means and the output of the first means and outputting the signal as a signal for communication.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the invention will now be described with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. In addition, the terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or chip designer, and the definitions should be made based on the contents throughout the present specification.

1 is a view showing the configuration of a haptic communication device according to the present invention. Such a short-circuit communication device does not need a transceiver module for a separate short-circuit channel because it utilizes a traffic channel, and has a feature that enables point-to-point type of short-circuit communication between access devices in a wired / wireless communication system.

Referring to FIG. 1, the haptic communication device according to the present invention is largely composed of four blocks (blocks 110, 120, 140, and 160). The block 110 includes an IPN code generator 111 for generating an I arm PN (Pseudo Noise) code and a QPN code generator 112 for generating a Q arm PN code. The IPN codes generated by the IPN code generator 111 are applied to the frequency mixers 124, 146, 165. The QPN code generated by the QPN code generator 112 is applied to the frequency mixers 125,135. The frequency mixer 135 inputs the output of the QPN code generator 112 and mixes it with a value of "-1" and then applies the mixing result to the frequency mixers 145 and 164.

Block 120 classifies pilot data into a Walsh code, classifies it into a PN code, filters and amplifies the result, and adds the amplification result to traffic data and other short-circuit data to transmit the data over a channel. The block to execute. The frequency mixer 123 of the block 120 mixes the pilot data 121 with the pilot Walsh code generated by the pilot Walsh code generator 122 and outputs the mixed data to the frequency mixers 124 and 125. The frequency mixer 124 mixes the output of the frequency mixer 123 and the output of the IPN code generator 111, and the frequency mixer 125 mixes the output of the frequency mixer 123 and the output of the QPN code generator 112. Each output of the frequency mixers 124, 125 is filtered by a finite impulse response (FIR) filter 126, 127, amplified by amplifiers 128, 129, and then output as I arm pilot data Ips (t) and Q arm pilot data Qps (t). . The I-arm pilot data Ips (t) is applied to the adder 130 and added to the output of the adder 151 (the result of the addition of the I-arm traffic data and the summing line data) and then output. The Q-arm pilot data Qps (t) Is applied to the adder 131 and added to the output of the adder 152 (the result of the addition of the Q-arm traffic data and the summing line data).

Block 140 is a block that inputs traffic data, classifies it as a Walsh code, classifies it as a PN code, and performs filtering and amplification. The frequency mixer 144 of the block 140 mixes the traffic data 142 encoded and output by the encoder 141 with the pilot Walsh code generated by the traffic Walsh code generator 143 and outputs the mixed data to the frequency mixers 145 and 146. The frequency mixer 145 mixes the output of the frequency mixer 144 and the output of the frequency mixer 135, and the frequency mixer 146 mixes the output of the frequency mixer 144 and the output of the IPN code generator 111. Each output of the frequency mixers 145, 146 is filtered by FIR filters 147, 148, amplified by amplifiers 149, 150, and then output as I-arm traffic data Its (t) and Q-arm traffic data Qts (t). The I-arm traffic data Its (t) is applied to the adder 151 and added after being added to the I-arm voting line data Ios (t) which is the output of the amplifier 168. The Q-arm traffic data Qts (t) is applied to the adder 152. Then, it is added to the Q-arm hammering line data Qos (t) which is the output of the amplifier 169 and then output. In this case, the outputs of the adders 151 and 152 are applied to the inputs of the adders 130 and 131 described above.

Block 160 is a block that inputs other line data and classifies it as a Walsh code, classifies it as a PN code, and then performs filtering, amplifying, and outputting. The frequency mixer 163 of the block 160 mixes the mixed line data 161 with the mixed line Walsh code generated by the mixed line Walsh code generator 162 and outputs the mixed line data 161 to the frequency mixers 164 and 165. The frequency mixer 164 mixes the output of the frequency mixer 163 and the output of the frequency mixer 135, and the frequency mixer 165 mixes the output of the frequency mixer 163 and the output of the IPN code generator 111. The respective outputs of the frequency mixers 164 and 165 are filtered by the FIR filters 166 and 167, and amplified by the amplifiers 168 and 169, and then output as the I-arm mixed line data Ios (t) and the Q-arm mixed line data Qos (t). The I-arm hammering line data Ios (t) is applied to the adder 151 and added to the I-arm traffic data Its (t) which is the output of the amplifier 149 and then output to the adder 130, and the Q-arm hammering signal Qos (t). ) Is applied to the adder 152 and added to the Q-arm traffic data Qts (t) which is the output of the above-described amplifier 150 and then output to the adder 131.

The communication apparatus according to the present invention as described above is largely composed of three channels, that is, the pilot channel, traffic channel, and other short-circuit channel. The data of each channel (pilot data, traffic data, rudder line data) are classified as Walsh codes and each of the classified data is classified as PN codes. Each of the data classified as described above is added by the adders 151, 152, 130 and 131 and then output. The outputs of the adders 130 and 131 are modulated by an RF carrier and then wirelessly transmitted and received by the antenna of the power station. Then, the signal received from the power station is classified into each channel, the pilot channel, traffic channel, and call line channel by despreading through carrier demodulation, and is inputted to the equipment connected through the wired link.

As described above, the present invention enables transmission and reception of other short-circuit data even when a separate transceiver for configuring the other short-circuit channel is not provided in the wireless communication network. Accordingly, even in the case where the wireless communication network does not have a separate transceiver for other short circuit communication, there is an advantage that the short circuit communication can be performed. In addition, as other short-circuit communication is required, there is an advantage of preventing the bulky communication equipment.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
