Design and Implementation of Synchronization Detection for IEEE 802.15.3c

Abstract

In this paper, a jointed preamble/boundary detection and fractional carrier frequency offset (CFO) estimation design is presented which supports dual SC/HSI modes of IEEE 802.15.3c applications. Based on correlation based algorithms which utilizes the structure of preamble, an efficiency architecture is proposed which realizes synchronization detection with a sequential detection scheme and only single hardware for dual modes and three detection operations. In order to achieve the requirement of sampling rate, the architecture is 8x parallelism and operates at 330 MHz clock rate. The total gate count is 189k in 65 nm 1P9M CMOS process with power consumption of 60.16 mW including memory elements which occupies 63.26 % and can be shared with the frequency domain equalizer (FDE).
