In this paper, simple analog carrier recovery circuits are proposed for BPS
K and QPSK reception. Theoretical analysis and simulations using an SPW (si
gnal processing work-station) validate the feasibility of these circuits. P
ractical circuits are also given to implement the control signal. The propo
sed circuits are especially suitable for receivers using compact analog sig
nal processing means to receive high data bit-rate signals. (C) 2001 John W
