ABSTRACT
This paper addresses the effects of errors in symbol timing estimation on t
performance of space time coded systems. Fixed and uniformly distributed timing errors w
different variances are assumed. Furthermore, the improvement of timing estimates w
increase in signal to noise ratio is modeled to yield practical expectations of performan
This symbol timing–error is applied to a simple transmit diversity scheme using QPSK
8PSK modulations. This paper could be useful guide for definition of requirement in symb
timing systems used in space time coding systems.
