The interfering system detection and mitigation techniques are important topics for spectrum sharing among various radio systems. And also the interfering band estimation technique in shared wide frequency band is significant to help the interference mitigation technique. In this paper, an interfering band estimation technique is proposed. In order to detect the interfering band, the multi-band pulse...
A wireless technology is required to realize robust transmission of medical images like a radiography image over noisy environment. The use of error correction technique is essential for realizing such a reliable communication, in which a suitable channel coding is introduced to correct erroneous bits caused by passing through a noisy channel. However, the use of a channel code decreases its efficiency...
Ultra Wideband (UWB) is an attractive technique that enable sharing spectrum with other radio systems to spread spectrum extremely wideband. However, there are potential interferences among those using in the same frequency bands and close range. This paper discusses the interference DAA (Detection And Avoidance) technique for coexisting pulse based UWB and OFDM systems. In a UWB transmitter-receiver,...
This paper discusses an interference detection technique for ultra wideband (UWB) to share the spectrum with other radio system. A detection and avoidance (DAA) technique are required in UWB system from some countries regulations. In most of interference mitigation techniques, it is required to detect existence of interfering signal and its band. However, some band pass filters are needed to detect...
