A MATLAB-based site-specific quasi-deterministic (QD) channel model simulator for millimeter-wave systems. Generates spatially-consistent multipath channel data (PathGridData) by combining ray tracing with site-specific statistical parameters.
CPSQDSIM is distributed as a standalone Windows application. The application and the site-data package are distributed separately – download both, then follow the installation steps in the manual.
Standalone desktop GUI (Ver. 1.0) for generating channel data, exploring maps and multipath components, and exporting CSV files. Requires the matching MATLAB Runtime.

CPSQDSIM is a MATLAB-based site-specific quasi-deterministic (QD) channel model simulator developed by the Radio Signal Processing Laboratory at Niigata University. It generates grid-wise multipath component (MPC) datasets — called PathGridData — that describe the propagation channel at each grid point in a target area, enabling spatially-consistent channel simulation for millimeter-wave mobile systems.
The simulator combines deterministic information from ray tracing with site-specific statistical parameters (LSPs and SSPs) measured from field campaigns in Yokohama, enabling accurate reproduction of real-world propagation for 5G/6G mmWave system evaluation.

CPSQDSIM framework: Ray tracing output and optional user SSP/LSP are fed into the SSP Generator, LSP Generator, and Path Generation Engine to produce grid-wise PathGridData. The Path Generation Engine supports both site-general 3GPP map-based and site-specific CPS QD models.

CPSQDSIM uses site-specific LSPs and SSPs measured from field campaigns in Yokohama City, Japan. Parameters are available for both mm-Wave and Sub-6GHz bands.
