Introducing Bandwidth Efficient Frame Structure (BEFS) algorithm for IRIG-106

Telemetry systems used in remote devices follow a standard frame structure, IRIG-106 standard, for transmission of data efficiently. Data from various serial and analog channels are multiplexed to form the frame. Usually, the multiplexing is done by dedicating specific frame bytes to these channels manually in order to decrease output data rate. In this paper, BEFS algorithm is introduced that models IRIG-106 frame structure efficiently. Xilinx Spartan 3E series devices have been used to frame the acquired data at transmitted end and to de-frame the frame at receiving end. Channel analysis helps to observe the variation in output data rate with respect to various input parameters. It is concluded that this technique successfully lowers the data rate by efficiently managing the bandwidth.
