Waveform distortion due to reflections in high-speed digital signaling is a classical issue of the signal integrity especially for the multi-drop transmission system. In general, the reflection characteristics and improvement measures of the multi-drop transmission strongly depend on the topology of the system in question, such as bus-configuration, star, ring, and so on. In this paper, we discuss a method of RCL (Reflection Compensation Line), formally reported in [6] as a reflection cancelling scheme, that can be applied to the bus-type multi-drop transmission system, whose length of main bus segments and stub lines are all isometric. Assuming practical application of our RCL technique to high-speed digital signaling, data rate of over 10 Gbps, the optimal set of transmission parameters are deduced by means of numerical optimization algorithm, and the performance of the RCL is discussed.
