Effects of interline coupling on bit error rate for high-speed digital signal propagation on PCB

In this letter, we investigate the effects of interline coupling on the bit error rate (BER) for various combinations of the physical parameters of two parallel microstrip lines. Numerical results based on two signal recovery methods, the impulse sampling method and the integrate-sample-and-dump method, are generated to aid printed circuit board (PCB) design for high-frequency applications.
