Abstract
In this paper, we consider multiantenna energy detection
(ED) of nonnegative pulse-amplitude-modulated (PAM)
symbols suitable for low-power and low-complexity
short-range communication radios using a very wide
bandwidth or high centre frequency. We present a general
condition which leads to the cancellation of the spatial
cross products between the distinct PAM space-time coded
signals at the output of an ED-based multiantenna
diversity decoder. Moreover, it is shown that our
existing analysis approach for single antenna ED-PAM
systems in very wideband lognormal multipath fading
channels can be conveniently extended for fast evaluation
of spatial diversity gain and correlation effects between
antenna elements in multiantenna ED-PAM systems. The
error probability performance is illustrated for the
selected system parameters by using the proposed analysis
tool. The accuracy of the analysis approach is
demonstrated with appropriate simulations.
