VMCK Transmission System Design for SDR Applications

Abstract:

Very minimum chirp keying (VMCK) as a novel high bandwidth efficiency modulation scheme is implemented on small form factor (SFF) software-defined radio (SDR). The VMCK transmission system model is elaborated based on Simulink within Matlab. Also, the final demodulation data stream at the output of the VMCK transmission system shows good performance in simulation. The transmitter and the receiver are designed on the SDR platform. The VMCK baseband signals with 2.5MHz are transmitted from Matlab workspace by ROM block, and then the VMCK signals are ratio frequency (RF) modulated with 432MHz. In addition, the RF receiving intermediate frequency (IF) signals with 30MHz on the SDR platform. The VMCK transmission model is easy to implement and has strong properties to resist synchronization error.
