A mobile station (MS) antenna is typically undergoing random spatial motion as part of the typical usage which degrades the coherency of the received signal resulting in demodulation losses. However, in a fading environment, the random motion can be constructively exploited in a generalized likelihood ratio test (GLRT) processing scheme resulting in diversity gain. The key outcome is the observation...
This paper analysis the performances of a single antenna handheld receiver in detecting a signal in a Rayleigh multipath fading environment. If the antenna is spatially fixed during the time interval that the signal is sampled then signal coherency is maintained. However, the signal will be subject to statistically large fading losses. The alternative is to spatially translate the antenna along some...
The performances of a single moving antenna receiver in detecting a narrowband signal in a correlated Rayleigh fading is considered. The single moving antenna captures spatial samples during antenna displacement that provides a realization of a synthetic antenna array. It is shown that there is a net processing gain in applying synthetic antenna array over keeping antenna stationary. This processing...
