(2014-09-11)This research focuses on the design and implementation of a digital active phase modulator path of a polar transmitter in the case of orthogonal frequency division multiplex WLAN application. The phase modulation path of ...
-
(Texas A&M University, 2004-11-15)This thesis considers the analysis of system performance and resource allocation for a coded OFDM system over frequency selective fading channels. Due to the inseparable role taken by channel coding in a coded OFDM system, ...
-
(2019-11-05)This thesis considers the long-standing problem of Peak-to-Average-Power Ratio (PAPR) reduction in OFDM systems. Due to the nonlinear amplifiers commonly used, OFDM signals often will be distorted when they are transmitted. ...
-
(Texas A&M University, 2005-11-01)Design and analysis of random-like codes for various multiple-input and multiple-output communication systems are addressed in this work. Random-like codes have drawn significant interest because they offer ...
-
(2017-07-28)Vehicular communications form an important part of future intelligent transport systems. Wireless connectivity between vehicles can enhance safety in vehicular networks and enable new services such as adaptive traffic ...
-
(2019-07-12)Advancements in the field of wireless communications in the last few decades have made it an indispensable part of how human made entities, and by extension, humans interact with each other. The inherent lack of the need ...
-
(2017-07-26)Currently, there is a standardization process underway to design the fifth generation of wireless systems or 5G wireless systems. The ambitious targets set forth for 5G wireless systems call for novel approaches in all ...
-
(Texas A&M University, 2004-09-30)The presence of dispersive fading and inter-carrier interference (ICI) constitute the major impediment to reliable communications in orthogonal frequency-division multiplexing (OFDM) systems. Recently iterative (``Turbo'') ...
-
(2009-06-02)This dissertation deals with the design of bandwidth-efficient coding schemes with Low-Density Parity-Check (LDPC) for reliable wireless communications. Code design for wireless channels roughly falls into three categories: ...
-
(Texas A&M University, 2004-11-15)This research concerns analysis of system capacity, development of adaptive transmission schemes with known channel state information at the transmitter (CSIT) and design of new signal detection and channel estimation ...
-
(2019-11-13)Orthogonal Frequency Division Multiplexing (OFDM) is an approach for realizing high speed transmission of data. The OFDM modulation scheme has the advantage of providing high spectral efficiency in multicarrier transmission ...
-
(2012-02-14)In this dissertation, the problem of synchronization for OFDM-based wireless communication systems is studied. In the first part of this dissertation, the sensitivity of both single input single output (SISO) OFDM and ...
