I am working on project related to wireless standard LTE and DVB-RCS. I have simulated individual blocks like modulator or FEC in MATLAB but I have to simulate full system and for that I would like to know which software is proper to get correct results.
In general we distinguish between link level simulations, where (coded) data symbols are generated and the performance is evaluated for a single link, and system level simulations, where larger systems are evaluated without generating data symbols but instead simplified models for the behavior of the individual links are used. For example a mapping of SINR to outage probability. You could create such a model from the link level simulations that you already have implemented.
There are some open source implementations for LTE System Level Simulations you could adapt to your specific scenario, one I am familiar is Imtaphy:

Simulating a larger system by generating all the data symbols may be ambiguous.
Vienna lte simulator
Very good matlab simulator for LTE and LTE-A for both link and system level simulation and both UL and DL under academic use only.
For a system-level LTE-(A) simulator you may want to take a look at SimuLTE, http://www.simulte.com.
It is free for academic use. Check my RG paper for a paper that describes it.
I suggest latest version of Matlab, which has all the necessary functions required. There is also a complete example provided. There are other programs such as LTE-Sim (you can download from the internet free of charge) written in C language but it only works on Linux or Unix OS.
For DVB-RCS simulation some patches which can be used with ns2 simulator is available but mainly used o simulate the Bandwidth on Demand techniques used in DVB-RCS.
Commercially there are Software & Hardware like DVB-RCS Forward and Return Link Analyzer used to work on DVB-RCS standard. There is also an Emulator commercially available named DVB-RCS Terminal Emulator which can emulate many DVB-RCS terminals and create a live DVB-RCS network environment. These are very useful tools to work on DVB-RCS technology or to develop DVB-RCS Hubs. However, they are commercially available and quite costly.
For pure research DVB-RCS patches in ns2 may help I feel.
Thank you for providing me valuable information. I will find patches in ns2 and try it for my work Thank you once again.
If you want to do a combined system simulation of LTE and DVB-RCS I would try ns-3. It has LENA and SNS-3.
