[USRP-users] GPS and frequency drift problems on TDMA receiver (E310)

2018-09-04 Thread David Zamorano Fernández via USRP-users
Hi all! We have implemented a TDMA receiver using the GPS signal to discipline the internal clock of the E310 and thus reduce frequency deviations. The system works fine, but in some cases, frequency drifts appear and the slots start to be erroneous (wrong CRC). The number of visible satellites ha

[USRP-users] TDMA receiver on E310

2018-07-19 Thread David Zamorano Fernández via USRP-users
Hi. We have implemented a TDMA receiver on an E310. We have to receive slots of 40 ms duration and we must capture and process each of them. These capture instants must be very precise, so we have used GPS to discipline the internal clock of the E310. What is the most appropriate stream mode for
