• #### Performance limits of brain machine interfaces ﻿

(2010)
Understanding the constraints governing information transfer between electrodes and neurons is crucial to the effective design of neural prostheses. In sensory prostheses such as cochlear implants, information is transferred ...
• #### Performance limits on beamforming with finite rate feedback for multiple antenna systems ﻿

(2002-11-20)
In this work, we address the problem of evaluating the outage performance of beamformers designed for multiple transmit and single receive antenna systems when quantized channel state information is available at the ...
• #### Performance of IEEE 802.11b Wireless LAN in an Emulated Mobile Channel ﻿

(2003-04-20)
The performance of 802.11b wireless LANs is well understood for indoor environments. However, their behavior in outdoor and mobile environments has remained largely unexplored. We have performed experiments to bridge this ...
• #### Performance of Iterative Multiuser Decoding and Channel Estimation in WCDMA Systems ﻿

(2000-05-20)
This paper studies the performance of iterative multiuser decoding, interference cancellation, and channel estimation techniques applicable to third generation WCDMA systems. The concept uses <i>a posteriori</i> probabilities ...
• #### Performance of Multi Binary Turbo-Codes on Nakagami Flat Fading Channels ﻿

(2006-05-01)
In this paper, performance in terms of Bit Error Rate (BER) and Frame Error Rate (FER) of multi binary turbo codes (MBTC) over Nakagami frequency nonselective fading channels are presented. The proposed MBTCs consist of ...
• #### Performance of multiprocessors and parallel algorithms: Quicksort, a case study ﻿

(1989)
Performance of parallel algorithms on multiprocessors has been traditionally analyzed by looking at either the algorithm or the architecture of the multiprocessor system. However, it is important to study the combined ...
• #### 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 ...
• #### Performance of Turbo-Codes on Nakagami Flat Fading (Radio) Transmission Channels ﻿

(2005-11-01)
The performance in terms of Bit Error Rate and Frame Error Rate for a turbo-coded system in Nakagami frequency-nonselective (flat) fading multipaths channels are presented. An efficient method for generating Nakagami- m ...
• #### Performance prediction of fast Fourier transform algorithms on loosely coupled multiprocessors ﻿

(1988)
In this study we examine the effects of implementing the Radix 2, the Radix 4 and the Prime Factor Fast Fourier Transform algorithms on two instances of message-based multiprocessor architectures. The machines we use are ...
• #### Performance study of parallel I/O systems ﻿

(1993)
The use of parallelism in I/O systems is becoming increasingly important as the performance gap between processors and disks continues to widen. This thesis studies the performance of multiple external merge sorts in an ...
• #### Perscriptive performance tuning: The R(X) approach ﻿

(1998)
Programmers often rely on performance analysis tools to provide feedback about the execution of their applications. However, the nature of this feedback is far from satisfactory. Often the feedback is purely descriptive ...
