Information is carried by changing the phase of the carrier. ->BPSK (Binary PSK): Uses two phases (0° and 180°). Very robust, but only 1 bit per symbol. ->QPSK (Quadrature PSK): Uses four phases (0°, ...
Abstract: This letter presents a simple closed-form expression to evaluate the error probability of binary fully-interleaved fading channels. The proposed expression ...
