“…For the case of single tone interferer, the bit-error probability (BEP) of DS-SS systems is derived in [15] and [16] for AWGN channels, and the comparison of several multiple-access techniques is made in [17] by ignoring the effects of additive noise. For the case of multiple tone interferers, an upper bound on the BEP was derived using the Chernoff bound in [18] and [19] for AWGN channels. The performance of UWB TH-SS systems is analyzed without additive noise in the presence of a single Gaussian interferer in [13] and with multiple tone interferers by means of the Gaussian approximation in [20].…”

Abstract-This paper evaluates the performance of wideband communication systems in the presence of narrowband interference (NBI). In particular, we derive closed-form bit-error probability expressions for spread-spectrum systems by approximating narrowband interferers as independent asynchronous tone interferers. The scenarios considered include additive white Gaussian noise channels, flat-fading channels, and frequency-selective multipath fading channels. For multipath fading channels, we develop a new analytical framework based on perturbation theory to analyze the performance of a Rake receiver in Nakagami-channels. Simulation results for NBI such as GSM and Bluetooth are in good agreement with our analytical results, showing the approach developed is useful for investigating the coexistence of ultrawide bandwidth systems with existing wireless systems.Index Terms-Code-division multiple-access (CDMA) systems, direct sequence (DS), matched filter (MF), narrowband interference (NBI), Rake reception, time-hopping (TH), ultrawide bandwidth (UWB) systems.

Smartphones with Bluetooth low energy (BLE, marketed as Bluetooth Smart) have been widely used. The BLE is a part of Bluetooth 4.0. It utilizes the 2.4 GHz band known as the industrial, scientific, and medical (ISM) band. The IEEE802.11 wireless local area network (WLAN) utilizes the same ISM band as BLE. Therefore, radio-frequency interference may arise with BLE and WLAN coexistence. In this paper, we focus on the interference between the WLAN beacon and the BLE advertising packet. We evaluate the bit error rate (BER) of the WLAN signal on the direct sequence spread spectrum (DSSS) modulation caused by interference with the BLE signal on the Gaussian minimum shift keying (GMSK) modulation by computer simulation. Additionally, we focus on the difference in frequency to investigate the effect of overlapping channels. Furthermore, we examine BER estimation by using the signal-to-interference ratio (SIR) assuming that the BLE signal is modeled as an additive white Gaussian noise (AWGN). Concerning the characteristic of the difference in frequency, we confirm the validity of these simulation results by experimental evaluation in the coexistence of the WLAN beacon and the BLE advertising packet. These results of simulation and experiment have shown that the difference in frequency is correlated with the interference of the BLE signal on the WLAN signal. Moreover, we have verified that the estimation of BER characteristics considering the difference in frequency by using SIR is possible.

“…For directsequence (DS) modulation, this ability has been investigated for several "canonical" forms of interference, including stationary Gaussian noise [11], pulsed Gaussian noise [15], tones [5], [13], narrowband noise [9], [12], [16], impulsive noise [1], [2], and multiple-access interference, e.g., [5], [14].…”
