Abstract :
Frequency hop codes represent a class of codes in which the signal is transmitted as a sine wave, whose frequency at any time, is one of a set of possible discrete values. A 2.0-μm CMOS technology transmitter which efficiently generates the signal for an extended hyperbolic congruential (EHC) frequency hop code is described. Minimal hardware is used to generate the constituent sine waves and the placement operator (the function which defines the sequence in which the sine waves are transmitted). The constituent sine waves are generated by characterizing them as phase increments, while the placement operator is evaluated by defining it as a recursive function
