Memory efficient set partitioning in hierarchical tree (MESH) for wavelet image compression
(The Institute of Electronics, Information and Communication Engineers., 2012-09)This paper presents a memory efficient version of set partitioning in hierarchical tree (SPIHT). The proposed coder called Memory Efficient SPIHT (MESH) uses a single re-usable list instead of three continuously growing ... -
Multi-carrier frequency hopping spread spectrum system with girth-six low-density parity-check codes
(Institute of Electrical and Electronics Engineering (IEEE), 2009-03-14)In this paper, a multicarrier frequency hopping spread spectrum (MCFH-SS) system with girth-six low-density parity-check (LDPC) codes is developed as forward error correction scheme to improve its anti-jamming (AJ) ... -

Receiver simplification in synchronous communication systems: Simulation study
(Institute of Electrical and Electronics Engineers (IEEE), 2008-12-02)This paper presents a simulation study for code-division multiplex system over time varying channels. The scheme investigated here uses a precoding technique in the transmitter depending on the channel information, so that ... -
Reduced complexity optimum detector for block data transmission systems
(The Institute of Electronics, Information and Communication Engineers, 2009-12-10)Block Data Transmission Systems (BDTS) are used in high-speed wireless communication systems with time dispersive channel characteristics. In such systems, blocks of data are separated by zeros to mitigate the effect of ... -
Row division method to generate QC-LDPC codes
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-05-24)To cut down the hardware implementation cost this paper presents an efficient method to construct large girth Quasi-Cyclic low density parity check (QCLDPC) codes. The row groups are paired two times the row weight, which ... -
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ... -
Waveform design for improved range and Doppler resolution in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02)The choice of a suitable transmit waveform is an important problem in radar design. This is so because the waveform controls resolution and clutter performance and also bears heavily on the system cost. Theoretical studies ...
