Experimental Evaluation of Interference from MB-OFDM UWB Systems to Narrowband Wireless Digital Transmission Systems

چکیده
Multi-band orthogonal frequency-division multipleaccess (MB-OFDM) is one of the UWB technologies that realize wireless personal network (WPAN). In this paper, we experimentally investigated the interference from MBOFDM signal to narrowband QPSK digital transmission system. The bit error rate (BER) performance of the narrowband QPSK system under the interference of UWB signal was evaluated, assuming the white Gaussian noise (AWGN) channel. The experimental results show a curve with BER degradation characteristics. The difference of the BER degradation characteristics according to the modulation parameter of the signal is discussed.

Narrowband Interference Suppression for MIMO MB-OFDM UWB Communication Systems
Ultrawideband (UWB) systems show excellent potential benefits when used in the design of high-speed digital wireless home networks. The constantly-increasing demand for higher data transmission rates can be satisfied by exploiting both multipathand spatial-diversity, using multiple-input multiple-output (MIMO) together with proper modulation and coding techniques. Unlike conventional MIMO OFDM ...

The ECMA-368 standard specifies multiband orthogonal frequency division multiplexing (MB-OFDM) as the definitive technology for high rate ultra-wideband (UWB) communications. Like other wireless systems, the performance of a correct data signals detection and decoding in MB-OFDM UWB is reduced by narrowband interference (NBI). A more specific problem of severity arises when interferences are pr...
