Yk. Jeong et Kb. Lee, Improved thresholds for wideband 4-ary FSK system (FLEX 3200) with limiter-discriminator-integrator receiver, ELECTR LETT, 35(7), 1999, pp. 531-533
Improved decision thresholds are proposed to enhance the performance of a w
ideband 4-ary FSK system. The improved thresholds provide a considerable pe
rformance improvement over conventional thresholds. Moreover, the performan
ce disparity between users is mitigated.
