| The standard ECMA-392 specifies a physical layer and a medium access sub-layer for wireless devices to operate in the TV frequency bands,wireless network working in TV white space(TVWS) has enhanced coverage range and robustness,and less power consumption.Based on the hardware of network devices using ECMA-392 technology including transceiver,digital signal process,and high level process module,control reference model based on MAC superframe structure is provided.A clock synchronization block is needed to make device synchronize in superframe period. An ECMA-392 network application established by TV broadcast operator is analyzed as an example. |
