Research Abstract

We have developed peak power reduction and low-complexity signal detection techniques for multiple-input multiple-output (MIMO) wireless communications systems. We have also analyzed the distribution of signal envelope of band-limited single-carrier systems and revealed its limitation in terms of power efficiency.
