Hello All,
Can anybody tell me what would be the diffference in the constellation
for pi/2-shift QPSK (not pi/4 QPSK). and normal QPSK.
This is one of the modulation types proposed as part of the TG3c
proposal(IEEE 802.15).
There is also mention about pi/2 BPSK, pi/2 QAM etc.
With regards to pi/2 BPSK, I understand that the constellation would
have four points but I was not sure on pi/2 shift QPSK and QAM?
Can anybody help me in this . Thanking you in advance.
Regards,
Iqbal
