Detailed Documentation
On November 12, 2010, yyf proposed a continuous phase modulation method with a correlation length of L=3, referred to as ***************CPM Modulation*****************. This technique maintains phase continuity between consecutive symbols by incorporating memory from previous symbols, where L=3 indicates that the phase depends on the current symbol plus two previous symbols. In code implementation, this typically involves using a shift register to store symbol history and applying a phase accumulation algorithm that ensures smooth phase transitions without abrupt jumps. The modulation scheme can be implemented using lookup tables for phase trajectories or real-time calculation of phase increments based on the symbol sequence.
