<p>PROBLEM TO BE SOLVED: To set a priority code string in its optimum range. SOLUTION: A parameter deciding part 28 confirms whether the resources sufficient to hold the information necessary for transmission are available. When the resources are found sufficient, parametersσandμwhich are used for deciding the priority code string of a probability distribution function are set to their initial values. When the resources are not sufficient, the value ofσis reduced while the value ofμis increased and these value are held at a parameter holding part 25. Then (n) pieces of uniform random numbers are generated by a uniform random number generation part 23. A probability distribution generation part 24 calculates a prescribed probability distribution function from the value held at the part 25 and the uniform random numbers generated by the part 23. Thus, the priority code string is decided from a certain distribution and then generated.</p> |
