摘要：
In this paper, we study the relationship between queuing delay for a random packet arrival process and physical layer parameters in a multiple access channel with multiple antennas at the input and output. Our main contribution is the derivation of a simple, analytical approximation for the average delay that clearly indicates the effect of number of transmit and receive antennas, transmission power, the packet arrival rate and the desired reliability. Comparison with numerical analysis indicates that the proposed analytical approximation of the delay is accurate for medium and large SNRs.
