A ZigBee Transceiver Used in 2.45 GHz Band and a 2K/4K/8K Multimode Fast Fourier Transformation for DVB-H ReceiversLee, Lung-hsuan 11 July 2007 (has links)
This thesis includes two topics. The first topic is a ZigBee transceiver used in 2.45 GHz
band design. The second topic is a 2K/4K/8K multimode fast Fourier transformation ( FFT ) for
DVB-H demodulators.
The first topic includes simulations and hardware design. The chip is a physical layer
design compliant with IEEE Std 802.15.4 standard, including a transmitter and a receiver for
2.45 GHz band. The measurement of the maximum power on silicon is about 731 £gW at 8
MHz. It is proved to be compliant with the low power consumption requirement specified by the
standard.
The second topic includes simulations and hardware design of an FFT for DVB-H
demodulators. This processor is based on a pipeline architecture with radix-2, radix-22 and
radix-23 computation element. We propose one sharing butterfly architecture to be used in the
variable length FFT processor.
