摘要: We introduce a framework for complex-valued signal processing such that all computations can be directly carried out in the complex domain. The framework, based on an elegant result due to Brandwood, allows easy derivation of many algorithms and their efficient analyses. demonstrate its application relative gradient updates independent component analysis using maximum likelihood discuss selection score functions within this framework.
