Why not? It is possible. Try to search for "Non-coherent sequence detection"
difference between detector and diode
the function of a diode detector is to detect stuff
diode detector for am demodulation
What the difference between envelop and coherent detection of AM signals
A photo detector is a sensor of light or other electromagnetic energy. See the link below for more info.
1) This is an example of coherent communication. 2) Of example this communication an is noncoherent.
fsk and psk
PSK stands for Portland Street Krew and its on the Eastside of Portland!
dpsk has lesser bw compared to psk
QPSK require less bandwidth compare to psk

The security key is the password for the wireless router. It'll show up if the wireless encryption is : WEP WPA-PSK (TKIP) WPA2-PSK(TKIP) WPA-PSK (AES) WPA2-PSK (AES).
See the related link below.
WPA-PSK is a type of encryption which must be used if you have choose between WEP and WPA-PSK. If you have an option to use WPA-PSK2 to use it because it's even better. PS: The problem with WEP is that it takes about 5 minutes to hack it. For WPA-PSK with password of at least 8 symbols it might take years if the password is complicated enough.
Envelope detection is used in an M-ary Frequency Shift Keying noncoherent modular because LOs are not required. Moreover, an estimate of 1dB of more power compared to the Frequency Shift Keying coherent demodulation.

PSK (Phase Shift Keying) is advantageous over FSK (Frequency Shift Keying) and ASK (Amplitude Shift Keying) because it provides higher data rates and better spectral efficiency. PSK is less susceptible to noise and interference since phase changes are more discernible than frequency or amplitude changes. PSK also allows for easier implementation in digital communication systems.
