simulator for simulating RFID localization and speed estimation

Dear friend,

What is the most suitable simulator for simulating RFID localization and speed estimation without using real hardware setup?

Your consideration and help are kindly appreciated. Thank you.

RFID localization and speed estimation? It involves many techniques. There is no easy answer. However, when talking about modeling the whole RFID system, matlab and ADS can be used.

if I want to use MATLAB what should I do?
