papr 3种方法 slm pts c变换

详 情 说 明

There are three methods when it comes to PAPR: SLM, PTS, and C transformation. These methods can be used to reduce the impact of high peak-to-average power ratio in communication systems. SLM, or selected mapping, involves transmitting multiple versions of the same signal with different phase shifts and then selecting the version with the lowest PAPR. PTS, or partial transmit sequence, involves dividing the original signal into several sub-blocks and then transmitting them separately with optimized phases. C transformation involves mapping the original signal into a different constellation, which can effectively reduce the PAPR. By utilizing these methods, communication systems can achieve better performance and stability.
