Effect of Channel Estimation Errors on Diversity-Multiplexing Tradeoff in Multiple Access Channels
Abstract— In this paper, multiple access channels are considered in which user data rates increase with the signal-to-noise ratio (SNR). To account for channel estimation errors,...

Space Division Multiple Access with a Sum Feedback Rate Constraint
On a multiantenna broadcast channel, simultaneous transmission to multiple users by joint beamforming and scheduling is capable of achieving high throughput, which grows double log...

The Gaussian Multiple Access Wire-Tap Channel
We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intellige...

Variations on Information Embedding in Multiple Access and Broadcast Channels
Information embedding (IE) is the transmission of information within a host signal subject to a distortion constraint. There are two types of embedding methods, namely irreversibl...

Error Exponent Regions for Gaussian Broadcast and Multiple-Access Channels
In modern communication systems, different users have different requirements for quality of service (QoS). In this work, QoS refers to the average codeword error probability experi...
