[SOLVED] wat is O-QPSK modulation .

[karthigowri]

wat is O-QPSK modulation .i already studied about oQPSK method. but i forget the concept .
pls anybody answer this.
Advance thanks to u.:|

Hi karthigowri.
O-QPSK: stand for Offset Quadrature Phase Shift Keying.
the advantage of this type is, the maximum phase shift provide by o-QPSK is 90 degree which will reduce the distortion in the receiver side leading to low BER. For further clarification there are many articles related to this topic is available in internet.

Hope it may helpful...

Let me clarify something.
Tye adavtage of O-QPSK over standard QPSK is that the evelope of the band-limirted modulated signal has much less variations.
This allows the use of nonlinear high power amplifiers in the transmitter without high spourious generation level.
Theoretical performance (BER vs. Eb/No) is the same.
