MMSE performance of carrierless AM/PM receiver with DFEs in presence of data-like cross-talks
نویسندگان
چکیده
In this paper, we determine the minimum meansquare error (MMSE) performance of a 2–D carrierless AM/PM (CAP) receiver with an ideal (analog feedforward and infinitelength baud-spaced cross-connected) decision feedback equalizer (DFE), in the presence of data-like cross-talks. The MMSE at the slicer is firstly derived for a generic multi-dimensional CAP system with cross-connected DFEs. However, this result requires the explicit factorization of the channel spectral matrix. In the case of the standard 2–D CAP line code, we are able to overcome this difficulty by exploiting the Hilbert transform-pair property of the shaping filters.

Three-dimensional Carrierless Am/pm Line Code for the Unshielded Twisted Pair Cables
The Carrierless AM/PM (CAP) modulation scheme is a viable alternative for high speed digital transmission for the HDSL/ADSL/VHDSL environments. In this paper, the conventional 2-D CAP system is expanded to a 3-D space. A 50% increase in the system throughput is achieved at the expense of added receiver complexity and some performance degradation. The 3-D signaling is obtained through a min-imax...
متن کاملCovariance Analysis of a vector tracking GPS receiver based on MMSE multiuser Detection
In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...
