Ambiguities arising from the model have also been analyzed, and solutions to them are provided. 文中还对通过信号模型估值存在的模糊问题进行了分析，并提出了解决办法。
However, an explicit algorithm flow for a complex signal model, which is usually used in communication theory, hasn't yet been given in literature. 在通信理论中经常使用到复数信号模型，但目前尚未有文献给出在该模型下明晰的算法流程。
