Abstract :
This paper presents an adaptive capability control technology to reduce training data in channel equalization, and designs a new space-time equalizer based on structure risk minimum criterion (SRM-STE). Simulation is carried out and the results are compared with a typical recursive least squares space-time equalizer (RLS-STE). It is concluded that SRM-STE has better tracking performance with much less training data, and only costs a little more computational complexity. This model adapts to mobile wireless communications.
