Delay bounded packet scheduling of bursty traffic over wireless channels
(2004-01-01)In this paper, we study minimal power transmission of bursty sources over wireless channels with constraints on mean queuing delay. The power minimizing schedulers adapt power and rate of transmission based on the queue ... -
On Diversity and Multiplexing Gain of Multiple Antenna Systems with Transmitter Channel Information
(2004-10-01)We quantify the multiplexing-diversity tradeoff of a multiple-input multiple-output (MIMO) system, when the channel state information (CSI) is known perfectly at the receiver and partially at the transmitter. The partial ... -
On the Asymptotic Performance of Multiple Antenna Channels with Fast Channel Feedback
(2005-10-01)In this paper, we analyze the asymptotic performance of multiple antenna channels where the transmitter has either perfect or finite bit channel state information. Using the diversitymultiplexing tradeoff to characterize ... -
Performance of Quantized Power-Control in Multiple Antenna Systems
(2004-06-01)In this paper, we analyze the outage probability of a single user system with multiple antennas at the transmitter, single antenna at the receiver, and finite rate feedback power control. The optimum power control is complex ... -
Power efficient broadcast scheduling with delay deadlines
(2004-10-01)In this paper, we present a framework for the design of minimal power schedulers that satisfy average packet delay bounds for multiple users in a Gaussian wireless broadcast channel. We completely characterize the achievable ... -
Power efficient transmission policies for multimedia traffic over wireless channels
(2002-04-20)The current and future wireless systems need to support a multitude of services with a wide range of data rates and reliability requirements. The limited battery resource at a mobile terminal coupled with the hostile ... -
Spreading and Power Allocation for Multiple Antenna Transmission using Decorrelating receivers
(2003-05-20)We propose a new scheme for multiple antenna transmission in the context of spread spectrum signaling. The new scheme consists of using shifted Gold sequences to modulate independent information on the multiple antennas. ... -
Spreading and Power Control for Multiple Antenna Transmit Diversity
(1999-04-20)This thesis proposes a new transmission scheme for multiple antenna transmission at the base station of a wireless cellular system. We develop our new scheme in a wideband CDMA framework using multiple phases of Gold codes ...
