“…1]. It is considered to be one of the severe noises on wireless communication systems and due to its wide band nature; it may cause degradation on the Quality of service for wireless communication systems such as Bluetooth, Universal Mobile Telecommunication Systems (UMTS) and Digital Video Broadcasting-Terrestrial [20]. Impulsive noise can be generated by natural sources such as lightening and ice breaking.…”

Gaussian Frequency Shift Keying (GFSK), a special case of Continuous Phase Modulation (CPM) schemes, is the modulation scheme chosen for achieving basic data rate of 1 Mbps with Bluetooth receivers. In this article, we present a new non-coherent demodulation technique based on the Extended Kalman Filter (EKF) that does not require the knowledge of the modulation index to detect the GFSK modulated signal in Bluetooth receivers. The paper examines the performance of our proposed receiver in the presence of Non-Gaussian impulsive noise since this type of noise is considered to be a severe noise for wireless technologies including Bluetooth. Bit Error Rate (BER) was used as the measurement metric for the performance for our proposed receiver at the physical level while Packet Error Rate (PER) and Residual Bit Error Rate (RBER) were used as the measurement metrics at the system level. Experimental results obtained for the Extended Kalman Filter detector for Non-Gaussian noise are provided.

“…As an example, in [4] a complete system, composed of a digital noise generator and a digital to analogue converter, which produces white Gaussian noise and offers a maximum generation frequency equal to 500 kS/s is proposed. Further examples of systems that produce the noise in analogue form can be found in [5,6].…”

“…Some contributions to the theory of coloured noise generation can be found in [4,[10][11][12][13]. The scientific literature also proposes prototypes that face the issue of coloured noise generation [2,5,6,14]. In particular, in [2] a low performance digital circuit for the generation of comb filtered noise implemented using small-scale integration logic is proposed.…”
