The IEEE 802.15.4 is defined as a Low-Rate Wireless Personal Area Network, which is also called ZigBee. The characteristics of ZigBee are low power consumption for battery life, extremely low cost, short-range operation.
According to 915 MHz Amplitude Shift Keying Modulation part of IEEE 802.15.4 ¡V 2006, we designed transmitter and receiver in base band part. In the later article, we will introduce my algorithm design, the Quantization and the Architecture in hard- ware implementation, the simulations, and the final verifying work of the layout that we did. Finally, we make a conclusion of this thesis, and we bring up the possible improvement in this design.
In my algorithm of the ZigBee receiver, I fined a new table to replace the original table of spec IEEE 802.15.4 to solve multi-sequence interference, which can improve the performance about 0.2 to 0.4dB.
My algorithm is lower 1.5dB than the Ideal receiver, which simulate in none carrier frequency offset (CFO) and none sample time offset, but both of mine are biggest. Then, my architecture implementation in hardware is lower about 1.5dB than my algorithm.
Completed the hardware circuit design and simulations, I applied for a layout in 0.18-um CMOS technology.
