Abstract :
A novel, uneven protection phase shift keying technique is proposed for the encoding of the required modulation scheme in an adaptive modem arrangement, which exhibits an improved performance in comparison to previously proposed schemes. The performance is derived numerically and a system dependent optimisation is presented. A benefit of 5 dB is achieved in a Rayleigh channel
