(Feher-patented Quadrature Phase Shift Keying), which are designed to reduce interference and out-of-band emissions. Spread Spectrum (SS)

Feher invented a modulation variant where the in-phase (I) and quadrature (Q) pulses are cross-correlated. This eliminates the 180-degree phase jumps. The result is a constant envelope signal that can be amplified by a 1-watt Class C amplifier to produce the same spectral containment as a 10-watt linear amplifier using standard QPSK. wireless digital communication kamilo feher pdf

This book provides a comprehensive overview of wireless digital communication systems, focusing on modulation and spread spectrum techniques. Feher's work is a classic in the field, and the book has been widely used as a reference and textbook. (Feher-patented Quadrature Phase Shift Keying)
