International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Blind adaptive equalization with application for Non-Linearly Amplified (NLA) quadrature
amplitude modulation (QAM) systems in multipath selective fading channels is presented.
With an offset sampling strategy in the receiver, the proposed blind equalization using
Constant Modulus Algorithm (CMA) exhibits a fast convergent speed for a family of
quadrature modulated systems in NLA and multipath fading channels. Feher’s patented
Quadrature Phase Shift Keying (FQPSK) and Feher’s Quadrature Amplitude Modulation
(FQAM) which correspond respectively to 4-state and 16-state QAM are used due to their
higher Radio Frequency (RF) power and spectral efficiency in NLA channel. It has been
shown that blind adaptive equalization can significantly open the eye signals in multipath
frequency selective fading channels.
