摘      要：An onboard telemetry system has access to a limited wireless bandwidth due to a high-speed airborne vehicle and large channel changing characteristics. The inefficiency of data placement happens at the transmission end if there is a large deviation between the packet rate and the frame rate for serial channels. For one of the current examples, the data rate of the transmitted signal can be decreased from 22 Mbps by straightforward placement in the major frame and to 3 Mbps using the novel algorithm introduced in this paper. The mathematical model in the subject is termed the bandwidth-efficient frame structure algorithm. A Xilinx Spartan 3E series has been used to frame the acquired data at the transmitting end and to deframe at the receiving end. The Inter-Range Instrumentation Group 106 standard has been used for the frame structure.
