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.
