Abstract
Multi-packet transmission from a single node to multiple destinations by exploiting the spatial dimension of the channel is a promising technique to increase the capacity of wireless networks. From the link layer point of view, this feature is known as Transmit Spatial Division Multiple Access (TxSDMA) and is supported by the use of multiple smart antennas at the transmitter. In this paper we analyze the impact of the buffer size on the performance of TxSDMA systems under QoS constraints. Results provide further insights in the cross-relations between the number of antennas, number of active users and the buffer size. The analysis done is based on a novel TxSDMA queueing model that, despite its simplicity, provides very accurate results for the range of situations in which TxSDMA systems work.
