In this article, we present a modular approximation methodology for efficient fixed-point hardware implementation of the sigmoid function. Our design consists of three modules: piecewise linear (PWL) ...

Dual- (L5 (1.164-1.188 GHz) and L1 (1.565-1.585 GHz)) and single- (L5) band Circularly Polarized (CP) Rectangular Dielectric Resonator Antennas (RDRAs) for ground terminal of navigation satellite ...
