A physical layer implementation of IEEE 802.22 prototype

In this paper, we present a recently developed physical layer implementation of IEEE 802.22 prototype. The prototype includes the following components: a channel (CH) unit, a Medium Access Control Layer (MAC) Control unit, a Global Positioning System (GPS) unit and a Radio Frequency (RF) control unit. The prototype is developed in a flexible and scalable platform to enable future enhancement for higher data rate application. In order to achieve higher data rate, the prototype is designed to accommodate multiple channel units for multiple channel access capability. A channel unit consists of a MAC Layer unit, a Physical Layer (PHY) unit and a Transceiver (TRX) unit. In this paper, we will concentrate our discussion on the physical layer implementation of IEEE 802.22 prototype and show the Bit Error Rate (BER) performances of the implemented physical layer of IEEE 802.22 prototype.
