| 摘要 |
The invention relates to a method of changing the encoding level of digital data transmitted between a transmitter and a receiver at a constant rate, said encoding level being determined as a function of the quality of the signal received by said receiver, an encoding level of rank 0 being defined as providing the highest degree of protection for said transmitted data and an encoding level of rank n-1 as providing a lowest degree of protection to said transmitted data. According to the invention, the method consists, during a fixed time of non-zero length, in preventing a changeover from an encoding level of rank n, where 0 ~ m < n-1, to an encoding level of rank m+q, where 0 < m+q ~ n-1, and where q is positive, after said received signal quality corresponds to encoding at the level m+q.
