On Superposition Coding for Wireless Broadcast Channels
This thesis investigates the performance of broadcast systems in which the transmitted signal is obtained by superposition of the independent user signals. We first focus on single-input single-output systems in additive white Gaussian noise channel. We study the performance of a superposition coding based transmission scheme for a 2-user broadcast system when the power allocated to each user i...
متن کاملCoherent Product Superposition for Downlink Multiuser MIMO
In a two-user broadcast channel where one user has full CSIR and the other has none, a recent result showed that TDMA is strictly suboptimal and a product superposition requiring non-coherent signaling achieves DoF gains under many antenna configurations. This work introduces product superposition in the domain of coherent signaling with pilots, demonstrates the advantages of product superposit...
متن کاملDifferentiated Rate Sceduling for MIMO Broadcast Channels∗
We consider the problem of differentiated rate scheduling for the fading MIMO Gaussian broadcast channel, in the sense that the rates required by different users must satisfy certain rational rate constraints. When full channel state information (CSI) is available at the transmitter, the problem can be readily solved using dirty paper coding (DPC) and convex optimization techniques on the dual ...
متن کاملHSDPA in Gaussian MIMO Broadcast Channels
We compare the achievable throughput of time division multiple access multiple-input multiple output (TDMAMIMO) scheme illustrated in 3rd generation partnership project (3GPP) MIMO technical report (TR), versus the sum-rate capacity of a space-time multiple access (STMA). These schemes have been proposed to improve 3GPP high speed downlink packet access (HSDPA) channel by employing multiple ant...
متن کاملFinite Rate Feedback MIMO Broadcast Channels
This paper summarizes recent results on the multiple antenna broadcast (downlink) channel with finite rate feedback of channel state information from each receiver. In this model, the receivers are assumed to have perfect channel knowledge, while the transmitter gains channel knowledge through a finite rate feedback channel from each receiver. The SNR degradation as a function of the feedback r...
