Abstract :
Quasi-orthogonal codes are implemented on the miniaturized passive sensor units, thus providing multiple access capabilities. A wireless temperature sensor system based on passive surface acoustic wave devices is designed and implemented. Experimental results obtained from a prototype system are in agreement with expected system response.
