- The delay constraints imposed by future wirelessapplications require a suitable metric for assessing their impacton the overall system performance. Since the classical Shannon’s ergodic capacity fails to do so, the so-called effective rate was recently established as a rigorous alternative. Yet, most priorrelevant works have considered only the typical case of Rayleighfading which allows for tractable manipulations. In this paper,we relax this assumption by considering the more general Rician fading model for multiple-input single-output (MISO) systems. Anew, analytical expression for the exact effective rate is derived, along with tractable expressions for the key parameters dictating the effective rate performance in the high and low signal-to-noise(SNR) regimes.

Konferensbidrag (refereegranskat)abstract
- In this paper, we elaborate on the ergodic sum rate of multiple-input multiple-output (MIMO) Nakagami-m fading channels with linear minimum mean square error (MMSE) receivers. For dual transmit antenna configurations, we present new, closed-form upper bounds on the ergodic sum rate of MMSE receivers. Moreover, we derive exact expressions for the two key parameters dictating the sum rate behavior in the low signal to noise ratio (SNR) regime, i.e., minimum energy per information bit to reliably convey any positive rate and the wideband slope. Our analytical results demonstrate the sub-optimality of linear MMSE receivers and provide useful insights into the impact of model parameters (e.g. number of antennas, fading parameters). © 2012 IEEE.
