A novel single-bit input all digital synchronizer and demodulator baseband processor for fast frequency hopping system

摘要

A new synchronization circuit with only one-bit input for fast frequency hopping systems, which is being implemented, is proposed in this paper. To companion with the one-bit input synchronizer, a one-bit input demodulator was also designed to test the viability of using single-bit input as a complete baseband processor for fast frequency hopping systems. Not only is the baseband chip low cost, it also provides a simpler analog front end. With those characteristics, the system becomes a low-cost overall system. The performance of the chip in terms of BER and synchronization offset is also comparable with other designs.
