Proficiency of Leaky Coaxial Cable-Based MIMO System Using Radiated Field Distribution

Abstract EN

This paper presents channel propagation characteristics of different multiple-input multiple-output (MIMO) systems using ray tracing approach in a confined area at 1.8 GHz according to the LTE-M standards.

Leaky coaxial cables were exploited at different transmitted locations to visualize the fluctuated radiated field under different polarization combinations.

In order to encounter this vision, the reflected and line-of-sight paths are under consideration for both vertically and horizontally polarized waves emitting from the leaky coaxial cables (LCXs).

Emphasis is given to understand the effect of LCX configuration on the channel correlation coefficient and capacity (C) in the confined area.

The exploration of experimental results reveals that the MIMO channel using LCXs has significant performance, specifically in the case of horizontal polarization.

Furthermore, it is inferred that for the longer distance between transmitter and receiver, the correlation coefficients have higher magnitude.
