IoT is a revolutionary technology which empowers physical devices with the ability to communicate and take collaborative decision without human intervention. Among the various protocol standards defined for IoT physical layer Bluetooth Low Energy is a promising one owing to its low power consumption. In this paper, a viterbi algorithm based BLE receiver is proposed where a joint viterbi detector and decoder is used rather than using two distinct viterbi processors for detection and decoding. The proposed model is simulated using Scilab and from the simulation results it is evident that the BER requirement of BLE is met at a SNR value of 5dBm. The performance of the viterbi algorithm based BLE receiver is found to be superior to other demodulation schemes used. The performance of BLE receiver using joint viterbi detector and decoder is on par with the receiver model using two viterbi processors.
