Low power implementation of edge-position modulation in focal plane image wireless infrared transmitting system

Edge-position modulation(EPM)scheme is introduced into focal plane image wireless infrared transmitting system as a substitute of traditional pulse-position modulation schemes to improve the bandwidth efficiency. A low power solution of EPM implemented by anti-fuse FPGA is proposed, which includes the design of input interface, buffer and runlength-limited(5, 12) (RLL)encoder state machine. The solutions of data recovery, pulse shrink and other Edge-position demodulation key techniques are proposed also. Using EPM scheme, the experiment system achieves the low power real time video data transmission of 320 × 240 pixels with the channel bandwidth of 24MHz. The application of wireless infrared export for focal plane image becomes more practical.
