one feedback, and one question.

Hi Sree,
Change the Pulse shaping filter type to NONE and you will see two levels of amplitude.
OOK is a special case of ASK where the amplitude levels are either 0 or 1.

HI Vinay

thanks for your help

I think I got it because I was not checking at what coerced rate the TX is sampling

thx for your help and I also have taken the OOk transceiver I will also check it

I wanted to ask If there are any examples of a transceiver Implemented on NI 5640 using the instrument Driver?

I will again be requiring your guidance If any problem occur.

Thx

Best Regards

Hi Vinay,

Thx for your advice,i tried it that worked excellent.The recieved constellation is fine now for the first time.

but my Rx bits have errors aproximatly 500 out of 1000 bits.i think this is because of synchronisation issue between Tx and Rx as i am transmiting and recieving in the same vi both in while loops.what can i do now in this issue.

Also tell me about the significance of 'samples to aquire'.

Best regards,

Airian
