Traffic-adaptive, flow-specific medium access for wireless networks
(Monterey, California. Naval Postgraduate School, 2009-09)
This dissertation pioneers the concept of traffic-adaptive, flow-specific medium access and demonstrates that it outperforms contention, non-contention and hybrid techniques. The novel traffic-adaptive Cooperative Wireless ...
A comparison of frequency offset estimation methods in Orthogonal Frequency Division Multiplexing (OFDM) systems
(Monterey California. Naval Postgraduate School, 2004-12)
OFDM is a modulation technique that achieves high data rates, increased bandwidth efficiency and robustness in multipath environments. However, OFDM has some disadvantages, such as sensitivity to channel fading, large peak ...
A comparison of timing methods in orthogonal frequency division multiplexing (OFDM) systems
(Monterey California. Naval Postgraduate School, 2004-09)
Orthogonal frequency division multiplexing (OFDM) is being used by wireless local area network (WLAN) standards, such as IEEE 802.11a, and wireless metropolitan area network (MAN) standards, such as IEEE 802.16a. OFDM is ...
Kill vehicle effectiveness for boost phase interception of ballistic missiles
(Monterey, California. Naval Postgraduate School, 2004-06)
Boost phase interception of ballistic missiles is envisioned as the primary response of the layered defense architecture implemented in the ballistic missile defense system. A limited time frame in which to take action and ...
Reed-Muller codes in error correction in wireless adhoc networks
(Monterey California. Naval Postgraduate School, 2004-03)
The IEEE 802.11a standard uses a coded orthogonal frequency division multi-plexing (COFDM) scheme in the 5-GHz band to support data rates up to 54 Mbps. The COFDM was chosen because of its robustness to multipath fading ...
JPEG2000 image compression and error resilience for transmission over wireless channels
(Monterey California. Naval Postgraduate School, 2002-03)
This thesis examines the compression performance of the JPEG2000 standard for image transmission over noisy channels. Other features of the standard, such as error resilience and region of interest, have been studied and ...
