本文主要研究一种只靠随机交织器来区分用户并让用户在时间、频率、码等同时共享整个资源,即叫交织多址技术,简称IDMA。本文介绍IDMA接口在ADSP-218X系列DSP芯片中的设计与应用,提出一种优化功率分配方式来提高整个系统的频谱效益并设计出一些降低实现复杂度的方法。此种方法可简化系统设计程序,降低运营成本。 This paper mainly studies a random interleaver to distinguish between users and allow users to share the entire resource at the same time, frequency, code, etc., called interleaving multiple access technology, referred to as IDMA. This article describes the IDMA interface in the ADSP-218X series DSP chip design and application of a power optimization approach proposed to improve the spectrum efficiency of the entire system and design to reduce some of the complexity of the realization of the method. This approach simplifies system design and reduces operational costs.
