Hence, especially in \"data only\" networks, an efficient uplink scheduling must not be neglected in the network design. Although not yet well covered in the literature, this area appears to gain importance especially in the face of high speed uplink packet access (HSUPA) radio link design for future wireless systems. In this work we study an uplink scheduling scheme from the information theoretic and queueing theoretic point of view. The objective of the cross-layer (Goldsmith, A.J. et al., 2003) scheduling approach we present is the stability of bit-queues awaiting their transmission at every user node. With this approach is associated an optimization problem of maximizing the weighted sum of rates, where the weights express the intensity of packet-traffics at every user node. An important property characterizing our approach is considering only spatial channelization of users, i.e. allocating user signals within one successive interference cancellation (SIC) order fixed over a certain time interval T. We show, that despite this neglection of time sharing technique, it is possible to achieve an overall optimal stability achieving scheduling for every set of user rate weights. Furthermore, we show that the choice of the SIC-order allowing for the optimal scheduling is independent of user channels and that the associated optimization problem over transmit covariance matrices is convex.","PeriodicalId":332887,"journal":{"name":"Proceedings of the 3rd IEEE International Symposium on Signal Processing and Information Technology (IEEE Cat.

The hardware demonstrator was developed and realized at our institute. It enables the multiple input multiple output (MIMO)-communication applications and is capable of transmitting arbitrary signals using the 8 transmit and 8 receive antennas in parallel. It operates in the 2.4 GHz ISM-band. The hardware concept is introduced and some design specifications are discussed. As an application example, we focus on one specific class of transmit diversity schemes: orthogonal space-time block codes (OSTBC). Channel and carrier offset estimation are essential tasks in coherent receivers. However, there are also some kind of error sources due to the imperfections of the employed algorithm. We show, by simulation and measurement results, that the OSTBC based systems are more sensitive to channel estimation errors and/or carrier frequency offsets than the conventional single transmit antenna systems. The consequence is that the diversity gain decreases significantly in the case of estimation errors.","PeriodicalId":332887,"journal":{"name":"Proceedings of the 3rd IEEE International Symposium on Signal Processing and Information Technology (IEEE Cat.
