Research ArticleOpen accessIn the abstractBit Error Rate Analysis of RS (7, 3) Coded Frequency Shift Keying Using SimulinkT.A. Shanmugasundaram, V. VijayabaskarBit Error Rate is an essential parameter to quantize the effectiveness of transceiver circuits used in low power, low duty cycle sensor nodes. BER can figure out their performance in terms of number of retransmissions, which keeps the node to consume its battery power undesirably rather than conserving it. Forward Error Correction schemes ensure the transceiver circuit to effectively perform … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 25 Mar 2015 · 7,051 accessesView PDFCite
