DEVICE FOR MODELING RADIO COMMUNICATION NETWORK Russian patent published in 2000 - IPC

FIELD: communication equipment. SUBSTANCE: number of allocated (free) channels in communication network is modeled by means of reverse counter 15. Number of user requests that receive denial of service in communication network and are sent to queue is modeled by reverse counter 16. Degree of correlation between received signals (after-effect of input sequence) is set by division coefficient of controlled divider 2. When division coefficient is equal to 1, model assumes empty after-effect. When division coefficient is greater than 6, model assumes complete after- effect. Pulses from controlled simple Poisson signal generator 1 are sent to addition input of reverse counter 15 through open AND gate 3. User request servicing is modeled by random pulse flow generator 17, which outputs pulses to subtraction input of reverse counter 15 through open AND gate 9. when no free channel is available in network, AND gates 3 and 9 are closed, while AND gate 5 is opened, so that pulses from generator 1 are sent to addition input of reverse counter 16 through AND gate 5. User requests sent to queue, when all channels of network are allocated, are modeled by means of random sequence flow generator 17, which outputs pulses to subtraction input of reverse counter 16 through AND gate 8. AND gate 8 is opened, when at least one request is present. EFFECT: possibility to model operations of radio communication network without reserved channels under different interaction of received signals. 2 cl, 2 dwg
