TMDSLCDK138: Signal Processing in OMAP LCDK kit

Sagnik Basu

Part Number: TMDSLCDK138

Hi.

So I want to implement a channel equaliser in TI LCDK DSP kit. I have read articles regarding implementing FIR filters for channel model. I want to implement a constant modulus algorithm for blind channel equalisation.

Is there any literature which may help me in this project?

Also, if I say generate some IQ data with noise in MATLAB, is there a way I can serially transfer this data from PC to LCDK kit through USB?

Thanks for all your help.

Sagnik,

We do have FIR filtering function in the TI C674x DSPLIB provided for this device. you can start by looking at that implementation to see if you can use that. For input, we have ADC (AIC3106) on the LCDK which you can use to provide input data.

you can also refer to this training text for filter design on C6748:

Regards,
Rahul

PS: also refer filterpro a webbench to design filters.
