Wave from mapped multiplexing: an alternative methodology for multiplexing plesiochronous channels.
Abstract
From the above analysis, it is evident that implementing Weighted Mean Method (WMM) using a fixed point of reconstruction introduces a bias of the form (x?Tg2)Tg2(x - \frac{T_g}{2})^{\frac{T_g}{2}}(x?2Tg??)2Tg?? in the process of transition reconstruction. Despite this bias, WMM proves to be a better estimator compared to the corresponding Time Division Multiplexing (TDM) based system.
Importantly, the variance of the reconstruction error remains identical in both systems. Therefore, the WMM-based demultiplexer—designed such that each transition is reconstructed after a fixed interval ‘x’ from the preceding sample point—offers improved estimation accuracy over the TDM-based demultiplexer.
