Abstract:

This paper introduces a generalized time-reversed space-time block codes GTR-TRSTBC as both a conceptual tool to examine the impact of unequal power allocation in equalized single-carrier systems employing two transmit antennas and as a method for exploiting partial channel state information by the transmitter. The generalization involves unequal power allocation parameterized by rho. The criteria for selecting the optimum is minimizing the residual mean-squared error at the MMSE equalizer output. GTR-STBC is applied to measured channel impulse responses and a simple statistical channel model. The results show that 1 the optimum value of gives the best tradeoff between signal-to-noise ratio and ISI 2 equal power allocation may not be the optimum power allocation when channel state information is available and 3 the optimum profile of over measured channels is significantly different than from that in statistical channel models.
