Multi-level data processing method and apparatus

摘要

The a{(n-1)*m}-bit binary data is arranged in upper (n-1) bits of multi-level data of m symbols, where m/-2. The (m-k)-bit binary data is converted into m bits according to a predetermined conversion rule and arranged in lower one bit of multi-level data of m symbols, where m is greater than k/-1, so as to convert (n*m-k)-bit data into one set of multi-level data made of m symbols. An independent claim is also included for multi-level processing apparatus.
