| Abstract(in English) | A positive integer code, with I times extend of length information at the rear of the codeword of a kernel integer code, is proposed. Then, it is shown that it encodes given positive integer n not longer than log^*_2n-α^*ω^*(n)+βlog_2ω^*(n)+d bits in time complexity O(logn・loglogn)(l=1) or O(logn)(l≧2), where log^*_2n=log_2n+log_2log_2n+log_2log_2log_2n+…, α^*=log_2log_2e.log^*_2 adds positive terms and zero term. ω^*(n)is the number of the terms in log^*_2n. β is a constant larger than one. Examples of proposed code are shown for the parameters of l=2, β=2, d=2.75 and l= 3, β=2, d=4.25. |
