Performance of Sequential Monte Carlo Receiver in Presence of IEEE 802.11 Interference
Performance consequence analysis of IEEE 802.11b interferer block for the sequential Monte Carlo (SMC) receiver has been accomplished to decide the receiver?s robustness as a GFSK receiver. The performance evaluation was conducted at the physical and system layers using MATLAB/Simulink as a simulation tool. Frame error rate (FER) and Bit error rate (BER) were used to quantify the SIR receiver. Two scenarios were performed at the physical layer: 1) A 50% interference rate aff ecting the Bluetooth system, 2) A 100% interference rate aff ecting the Bluetooth system. At the system layer, the packet drop rate caused by the interference was measured to determine the system robustness, while the BER evaluation measures the quality of processed packets. The results of the SIR receiver?s performance were compared to the limiter discriminator integrator (LDI) receiver, and to the Viterbi receiver. The analysis proved that at the physical layer and while having a 100% interference rate, the SIR receiver outperformed the LDI receiver by approximately 17 dB, and outperformed Viterbi receiver by nearly 12 dB in terms of BER. At the system layer and by experiencing the same conditions, the SIR receiver proved to have nearly 14 dB improvement over the LDI receiver and about 7 dB improvement over the Viterbi receiver in terms of FER. In addition, the assessment also showed that when the SIR receiver is affected by a 50% interferer signal, the SIR receiver exposed significant improvements over both referenced receivers. The SMC receiver has a significant capability of managing major networks interferences that are within proximity of GFSK network. All of the results validate the robustness of the SMC receiver. The receiver proved to have a substantial performance perfection compared to other existing receivers.
