摘要： A communication network system includes a communication line, a plurality of communication stations each having a node coupled to the communication line and a network controller coupled to the stations for controlling routing for communication messages between nodes. In one embodiment, the messages are sent from plural terminals connected with each node along with communication performance prerequisites. The communication performance prerequisites for a communication message are discriminated in the node which receives the message. Traffic in various routes between the nodes is continually measured in the communication stations and the measuring results are stored in a database storage unit. Future traffic in the various routes is predicted on the basis of the information on the continually measured traffic by the use of a predetermined algorithm and stored in the storage unit for use in determination of routes for communication messages on the basis of the result of the communication performance prerequisites discrimination and predetermined criteria with respect to the updated information on the predicted traffic in the storage unit.

摘要： A radio communication system and a traffic channel assignment method for realizing the assignment of traffic channels capable of improving the efficiency of use of frequency in the case where the traffic density is high and improving a radio link quality in the case where the traffic density is low. A base station judges the traffic density from a carrier to interference power ratio (CIR) on each channel capable of being selected as a traffic channel. In the case where the traffic density is low, a traffic channel assignment mode selecting an available channel having a greater CIR is assigned as a traffic channel to a mobile station. In the case where the traffic density is high, a traffic channel assignment mode selecting an available channel having a smaller CIR is assigned as a traffic channel to the mobile station. Thereby, it is possible to structure a radio communication system which can cope with the condition of the traffic density of the neighborhood.

摘要： There is provided a maximum likelihood decoding method, and an apparatus, capable of correcting burst errors caused by abrupt lowering of the signal amplitude. The soft decision maximum likelihood decoding method is a maximum likelihood decoding method for conducting maximum likelihood decoding on a received train resulting from addition of an error train to a transmission code train, which has been obtained by coding an information train by using convolutional codes on a transmission side. The soft decision maximum likelihood decoding method includes the step of making corrections by multiplying the soft decision likelihood metric having a multi-valued level, which has been obtained by soft decision likelihood metric from the received train, by weighting coefficients depending upon an instantaneous amplitude of the received signal, and the step of conducting maximum likelihood decoding by using corrected soft decision likelihood metric values. Thereby, it becomes possible to enhance the error correcting capability of error correcting apparatuses used in mobile radio communication or the like with severe fading. As a result, communication reliability is increased.

摘要： An adaptive digital filter is connected in parallel with a transmission system and includes a plurality of delay circuits, a nonrecursive digital filter having coefficient parameters of the delay circuits so as to approximate the characteristics of the transmission system, and a correction circuit for correcting the coefficient parameters of the nonrecursive digital filter. The adaptive digital filter further includes a first variable attenuator, a second variable attenuator and a comparator. The first variable attenuator receives an input signal for the adaptive digital filter, variably attenuates the input signal in response to a first control signal, and supplies an attenuated input signal to the transmission system and the nonrecursive digital filter. The second variable attenuator receives a difference between the output signals from the nonrecursive digital filter and the transmission system and variably attenuates the difference signal in response to a second control signal. The attenuated difference signal serves as an output of the adaptive digital filter. The comparator compares the level of the input signal with the level of the output signal from the transmission system and drives the first or second attenuator, which receives a lower level signal when the level difference exceeds a predetermined value.
