The Phase Estimation Algorithm of Arrival Phase Differences in Space-Time Coded Communication

다국어 초록 (Multilingual Abstract)

One objective in developing the next
generation of wireless communication systems is to increase
data rates and reliability. A promising way to achieve this is to
combine multiple-input and multiple-output signal processing
with a space-time coding scheme, which offers higher coding
and diversity gains and improves the spectrum efficiency and
reliability of a wireless communication system. It is noted,
however, that time delay differences and phase differences
among different channels increase symbol interference and
degrade system performance. In this letter, we investigate
phase differences and their effects on multiple-input and
multiple-output systems, and propose a compensation
algorithm for the Rayleigh fading model to minimize their
effects.
