Abstract

This paper investigates a wordlength effect on an adaptive phased array antenna using the Constant Modulus Algorithm (CMA). The antenna is a flat four-beam compact phased array whose main beam can be switched into four directions by using four one-bit phase shifters. A beam with maximum received power is exploited as an initial beam for CMA. The wordlength investigation will be shown in term of the signal constellations, SINR trajectories and antenna patterns. © 2005 IEEE.
