I have a project that requires Trellis/multi-symbol/CPM demodulation of a GFSK signal. This demod should:
1) Accept complex samples - I and Q are 32-bit floats at 10 samples per symbol
2) Perform course frequency correction, followed by FIR filter for bandwidth limiting
3) Perform symbol timing recovery, whose output is complex 1 samp/symbol
4) implement trellis at 1 samp per symbol, hard decision output (no SOVA required)
Given a specification of the modulation index and bandwidth time product, I will need you to:
1) Model an optimum demodulator and provide BER vs Eb/N0 curves.
2) Once the model is proven, conver the implementation to C/C++
3) Test the C/C++ implementation like you did with the model for the following characteristics:
* BER vs Eb/n0
* BER vs. frequency at Eb/n0 = 9. 5 dB
* Convergence time (in symbols) at Eb/n0 = 9.5 dB
* Benchmark on Zynq or similar platform and show CPU utilization. I can be flexible on platform/methodology if you do not have access to zynq
4) Deliver the code to me for exclusive licensing/use
You can skip the modeling part if you just want to go direct to C/C++ and you're confident in your abilities to do so effeciently.
If you big, please include links/descriptions to similar work.
Hi. I think as you said would be very good to go with the model in a simpler language let's say c# (could be matlab maybe too), then perform the port to c++. I have not worked directly with this kind of signals before, all DSP I've done is with images but I likely can handle it. I would need to study some parts however. I am programer but my brother studied telecommunications engineering. I can request help from him if needed. I don't have access to zynq I however have some knowledge of VHDL and Verilog. Time for project is just a rough estimate, could take longer.
Okay, i already got your project goal and i can start right away. But i have some questions. My completion rate is always 100% and i only bite what i can chew. Knock me please...

Dear Project Owner,
Greetings for the day!
Thank you for reviewing my bid.
I have gone through the details and will get it done quite comfortably.
I would like to have a discussion with you elaborating project requirements. So can we schedule a meeting over Skype or any other communication medium you prefer?
My Skype ID is: rohitjain007
We have good experience of working on C++
We can start the job immediately once you award it to us.
Kindly reply back to this message so that we can discuss the project further in detail and gain a better understanding of your vision.
We would surely hold true faith over our services and it would be our fete to be engaged with you in a long lasting relationship.
