PIXIL is a small footprint operating environment, complete with
PDA PIM applications, a browser and multimedia applications
for small handheld and flat-panel based devices.
The goal of this project is to explore the idea of point-based
radiosity, which is a shooting radiosity technique suggested by Mark
Harris at UNC. The primary idea is that features available in
graphics hardware can be utilized to perform radiosity calculations.
Facilities such as flat shading, diffuse lighting, projective
textures, and mipmapping can be used to replace traditional numerical
solutions for radiosity.
This paper examines the asymptotic (large sample) performance
of a family of non-data aided feedforward (NDA FF) nonlinear
least-squares (NLS) type carrier frequency estimators for burst-mode
phase shift keying (PSK) modulations transmitted through AWGN and
flat Ricean-fading channels. The asymptotic performance of these estimators
is established in closed-form expression and compared with the
modified Cram`er-Rao bound (MCRB). A best linear unbiased estimator
(BLUE), which exhibits the lowest asymptotic variance within the family
of NDA FF NLS-type estimators, is also proposed.
This program simulates the bit-error-rate (BER) performance of OSTBC
with L=4 antennas over the frequency flat Rayleigh block fading channel
The code is developed for real orthogonal design, code rate 1/2
modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.
