摘要
Wireless Communications is used in various applications and the number of wireless devices has also increased over the past several decades. However, wireless communication systems may be significantly affected by interference signal. In this paper, the carrier to noise ratio (CNR) or the bit error rate (BER) performance of Amplitude Modulation (AM), Frequency Modulation (FM), MPSK (M-array Phase Shift Keying), MFSK (M-array Frequency Shift Keying), Minimum Shift Keying (MSK) and Gaussian Minimum Shift Keying (GMSK) have been evaluated under sweep jamming as an intended interference. In addition, we measured the quality of received audio signal by perceptual evaluation of speech quality (PESQ). From the result of performance analysis, we concluded that orthogonal frequency-division multiplexing (OFDM) sweep jamming severely affects power of the transmission signal and chirp sweep jamming provided a strong influence over the phase and frequency of the transmission signal. By using our simulators, it is possible to determine an appropriate modulation scheme according to the channel environment. In addition, we know the parameter of jammer for blocking the unnecessary communications.
