My question concerns on the accuracy of the localization system which relies on measuring the TDoA of the signal using 4 beacons spaced between 20 m (SBL for underwater...
Thanks to u Kaz, for your effort. 1- Yes, i think, because all the data are buffered and latter transmitted. So i suppose all the data are correctly transmitted. 2....
Kaz, thanks again for ur reply and patience. For a non dsp guy some concepts are hard to follow, unfortunately. Below i describe my system so far so maybe provides...
Thanks Kaz. Can you please provide an example where a shifting in phase occurs even if the sampling clocks are stable. I was thinking for an example like this: ...
Thanks Kaz, For the first point i have to make sure that the both of the system perform the requested sampling rate.This can cause me a frequency shift. I dont...
Yes you are right, more precisely underwater comms in which speed of sound is greater.But yet mulitpath is still present and a big issue. We used to put some pause...
Hello Katz,thanks again. In practice my system is wireless, communication between two laptops using acoustic waves. What i do at the transmitter is to generate a...
Hi Kaz,Thanks for the reply. Onestly i dont correctly understand what do u mean by reomote comms. Tx and Rx can run in different platforms, e.g., pc and embedded...
Hi folks,I wanted to ask what exactly is meant for phase recovery of signal (at least intuitively). I have a working example of an acoustic fsk modulation and demodulation...
Thank you very much Tim,You mean more than one sample per bit period for SNR calculation, or preamble detection. Currently i have some miss-understanding how the...
Thank you very much for your prompt response. What does the
"oversampled" means and how can be archived. If using fsk
autocorrelation for detection I think it...
