See the question "What is QPSK".
If you want the difference between QPSK and some other modulation system, you'll need to name the other one.

What is the difference between oqpsk and qpsk?
the phase shift allowed in OQPSK is 900 whereas in QPSK it is 1800 . QPSK is used in uplink whereas OQPSK is used in downlink.
What is the difference between PSK and QPSK?
in psk,we use only single type of phase shift for a bit transition. in qpsk,we use 4 types of phase shifts for a bit transition.
What is the advantage of qpsk over psk?
QPSK require less bandwidth compare to psk
What are the disadvantage of qpsk?
Disadvantages of QPSK are large interchannel interferences, required filtering, consonant synchronization, and more bandwidth usage for transmitting power. Its disadvantages are just matters of consumption and constant fine-tuning.
What is the difference between BPSK and QPSK?
Binary PSKQPSK.1. Two different phases are used torepresent two binary values.1. Four different phases are used to represent two binary values.2. Each signal element represents only one bit.2. Each signal element representstwo bits
What is the difference between oqpsk and qpsk?
the phase shift allowed in OQPSK is 900 whereas in QPSK it is 1800 . QPSK is used in uplink whereas OQPSK is used in downlink.
What is the difference between QPSK and DPSK?
Qpsk has lesser bw than dpsk but has more probability in error than dpsk.
What is the difference between PSK and QPSK?
in psk,we use only single type of phase shift for a bit transition. in qpsk,we use 4 types of phase shifts for a bit transition.
What are the difference between QAM and QPSK?
in qpsk we are using phases for representation of messages while in qam we hav amplitude levels. in qpsk 2 bits per symbol is used with four different phases. in qam depanding on type i.e 16 qam,64 qam,256 qam how many amplitude levels to be used accordingly i.e 16,64,256. sonender kumar
What is QPSK?
QPSK = Quadrature Phase Shift Keying In QPSK amplitude are not much.so the carrier is constant. transmission rate is higher when compared with PSK
What is the bit rate of a QPSK compared to BPSK?
bit error is same for QPSK and BPSK. :
What is the advantage of qpsk over psk?
QPSK require less bandwidth compare to psk
Why Qpsk?
QPSK is used in CDMA because it helps achieve higher data rates. It is much better than simple PSK.
What are the modulation tecniques in mobile communication?
qpsk modulation
What is the modulation technique used in pdh as nec equipment?
QPSK
Which is the best modulation technique in terms of message carrying efficiency?
qpsk
What are the disadvantage of qpsk?
Disadvantages of QPSK are large interchannel interferences, required filtering, consonant synchronization, and more bandwidth usage for transmitting power. Its disadvantages are just matters of consumption and constant fine-tuning.
