GMSK Reception with Flex Gecko

I would like to receive GSM signals with Flex Gecko.

Can the Flex Gecko demodulator be configured for coherent reception of G-MSK?

If so, what parameters do I need to configure?

Thank you

Re: GMSK Reception with Flex Gecko

ir,

 

There is no coherent MSK detection on the Flex gecko.

However there is a muti-baud differential detection whose performance is very close to the coherent demodulator's.

 

Currently MSK reception is disabled in the radio configurator. I expect this to be enabled in the near future. In the meantime you may want to experiment with OQPSK as the performance of this scheme will match the MSK's for the same DR. 

 

I hope this is of help,

Regards,

Zoltan
