(1):digital signal processing with fpga.

(2):software radio algorithm with fpga.

hope you can connect me with icq(584698537).

thanks

I interested in this subject. My thesis is about SDR receiver and I need to find some component algorithms such as LPF,digital local oscilator and digital mixer codes. I am comforming this project but its realy hard for me. If you have any information about this subject, please help me:)

Go here:

Read the ESC papers and slides, and look at the LFSR tutorial and documents.

Cheers,

Dave

Thanks Dave but I need lpf and digital mixer vhdl code for quartus II and if I find these codes, I will apply multiplication operation and embed fbga and design new component

Antenna--> RF amp-->ADC-->mixer-->digital lpf-->dsp(demod)-->DAC-->audio amp

Its all described in those documents. Look at the images in the ESC slides.

Digital mixer = NCO plus multiplier, with bit widths determined by your application.

The LPF can be implemented using the FIR compiler, or you can create it yourself per the example code with the ESC papers and the LFSR papers.

Cheers,

Dave
