A method of forming a constellation design, and a receiver having both a
processor that generates the constellation design and having a
comparator. The particular constellation design described herein reduces
errors resulting from a noisy communication channel. The generated
constellation design includes a minimum threshold and a maximum threshold
representing a variable range for each of a plurality of possible message
levels. The constellation design accounts for the interrelationship
between signal strength and noise in the communication channel. The
comparator identifies the transmitted message by comparing the received
signal with the generated constellation design.
