We have now released the fourth episode of the podcast Wireless Future, with the following abstract:
We are creating a society that is increasingly reliant on access to wireless connectivity. In Sweden, you can barely pay for parking without a mobile phone. Will this wireless future have a negative impact on the security of our data and privacy? In this episode, Emil Björnson and Erik G. Larsson discuss security threats to wireless technology, including eavesdropping, jamming, and spoofing. What impact can these illegitimate techniques have on our lives and what do we need to be aware of?

Dear sir, I have question not related to this topic. Sir why are we using QAM in 5G NR, and not M-ary PSK. Even QAM has higher BER compared to M-ary PSK. Is this due to transmitter receiver simplicity?
As far as I know, the error probability is smaller with M-QAM than with M-PSK, if the same value is used. By using both the phase and amplitude domains, the distance between the constellation points can be increased and this leads to lower error probability. Here is one page showing how 16-QAM has lower error probability than 16-PSK: http://www.dsplog.com/2008/03/29/comparing-16psk-vs-16qam-for-symbol-error-rate/
Thanks very much sir.
