HW/SW Codesign QPSK Transmitter and and Receiver Example runing problems
Im using matlab 2017b I have finish the hw sw co dedign demo successfully However, i find that this demo require transmitter keep working during the entire experiment, that is, continuous transmitting. if i stop the transmitter (for example,disable the adi rf som transmitter block for a period of time),the RECIEVER will NOT accept any data even after tx start working again, how can i deal with this problem ps hardware is picozed sdr vivado is 2016.4

Hi Yang,
This example has been designed as a streaming system, and the receiver has not been designed to cope with interruptions to the data stream. I'm afraid if you would like to make this suitable for a bursty system, you will need to investigate changes to the receiver yourself.
Regards,
Neil

Hi Yang,
I'm afraid the example is the same in R2018b and R2019a. To modify this to a burst-capable example you will need to investigate the changes yourself.
We'll note your requirement and think about future changes.
Kind regards,
Neil

thank you for your answer
ln addition, i find that in demo hw sw co design implementation of ads_b(similiar with qpsk demo), the system runs well at 1090mhz and real plane signals are recieved. that is, the model works well in burst mode (because real plane broadcast ads_b signals in bursty mode)
my question is why this model can run on bursty mode while the qpsk demo can not.
regards

Hi Yang,
The ADS-B model has been designed to work with bursty signals. The QPSK model has been designed to work with streaming signals. To modify this to a burst-capable example you will need to investigate the changes yourself.
Thanks,
Neil
