摘要

在本文中，我们证明了编码CPM方案的“实用主义”方法会遭受重大的容量损失。通过选择一种不同于目前所采用的自然映射或灰度映射的适当映射，可以大大减少这种损失。我们建议在CPM调制器中添加一个线性反馈，通过容量参数进行优化，从而可以在CPM容量的1 dB内实现性能。

A Pragmatic Approach to Coded Continuous-Phase Modulation

In this paper, we show that a "pragmatic" approach to coded CPM schemes suffers from a significant capacity loss. This loss can be greatly reduced by choosing an appropriate mapping different from natural or Gray, adopted so far. We propose to add to the CPM modulator a linear feedback, optimized through capacity arguments, that permits to achieve performance within 1 dB from the CPM capacity.
