WLAN and Bluetooth Coexistence: A Comparative Study of Convolutional Coding versus Turbo Coding
نویسندگان
چکیده
The IEEE 802.11g physical layer is based on coded orthogonal frequency division multiplexing (COFDM) using the industry standard [133 171] binary convolutional code. In the presence of Bluetooth interference this code struggles to provide good packet error rate (PER) performance. In this paper Turbo coding is considered as an alternative to convolutional coding. The results show that Turbo coding substantially improves the reliability of the Coded Orthogonal Frequency Division Multiplexing (COFDM) format in Bluetooth interference and can provide reducible PER performance at Signal to Interference Ratio (SIR) values down to 0 dB.
