An efficient preamble design for burst mode continuous phase modulation

Abstract

In this paper, an efficient preamble designed for the burst mode continuous phase modulation (CPM) signals is proposed. The innovative preamble is based on the combination of a single tone signal and a unique CPM signal. Like the preamble adopted in MIL-188-181B standard, the proposed preamble can estimate the carrier frequency and phase offset, and acquire the symbol timing and frame synchronization. The performance of the designed preamble is assessed by computer simulation. The experimental results is that their carrier frequency, phase and symbol timing gaps with their own Modified Cramer-Rao Bound (MCRB) are very small. The proposed preamble is a good choice for timing acquisition.
