Zero Forcing and Decision Feedback Detectors in MIMO Communication Channels and Their Applications to Frequency-Overlapped Multi-Carrier Signaling

摘要

This paper investigates noise enhancement fac- tors of a zero-forcing detector and a decision feedback detector for synchronous Multiple Input Multiple Output (MIMO) chan- nels. It is first shown that the Zero-forcing and decision feedback detectors can be implemented in a vector digital filter form, and the noise enhancement factors with the detectors can easily be calculated by using the vector digital filter form. This paper then applies the zero-forcing and decision feedback detectors to the signal detection of a frequency-overlapped multicarrier singal- ing (FOMS) system.
