In recent years, the worldwide progress of wireless communication technology has bringing great benefit and convenience to our people¡¦s life. Nowadays, people can use appliances of wireless communication in many fields, such as family-monitoring, automatic system, and smart-type device¡Ketc. However, in order to dealing with the need of low cost and low power communication, the researcher spend many years on developing the specification of IEEE 802.15.4 Low Rate-Wireless Personal Area Network (LR-WPAN) expected be applied in widespread use.
In this thesis, we focus on the baseband signal processing for the physical layer specification of the 868/915MHz mode of the IEEE 802.15.4 LR-WPAN. Our design blocks include packet detection, sampling point detection (energy detection), carrier frequency offset (CFO) compensation, carrier phase offset (CPO) compensation, and despreading algorithms. During the process of simulation, we¡¦ll examine whether our design match the criteria of standard such as sensitivity, packet format, and modulation. While our designs achieve the requirement of the standard, we start on quantization. Finally, we¡¦ll realize the algorithm in VHDL and examine it.
