Improved iterative detection and achieved throughputs of OFDM systems under imperfect channel estimation
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...

Polyhedral space generation and memory estimation from interface and memory models of real-time video systems
We present a tool and a methodology for estimating the memory storage requirement for synchronous real-time video processing systems. Typically, a designer will use the feedback i...

Outage Behavior of Discrete Memoryless Channels Under Channel Estimation Errors
Classically, communication systems are designed assuming perfect channel state information at the receiver and/or transmitter. However, in many practical situations, only an estim...
