PERFORMANCE AND CAPACITY COMPARISON BETWEEN HYBRID BLAST-STBC, VBLAST AND STBC SYSTEMS
(2012)
The hottest issue of next generation communication systems is data throughput improvement for any wireless channel conditions. MIMO systems are the key techniques for the next generation communication systems. BLAST systems ...
Performance Evaluation of MIMO Spatial Multiplexing Detection Techniques
(2012)
Multiple Input Multiple Output (MIMO) multiplexing is a promising technology that can greatly increase the channel capacity without additional spectral resources. The challenge is to design detection algorithms that can ...
Generalized PIC detector for distributed STBC under quasi-synchronization
(Scientific Research Publishing, 2012)
In this paper, we propose a Generalized Parallel Interference Cancelation (G-PIC) approach for the detection of D-STBC under Quasi-Synchronization in the case of any number of relay nodes with just statistical information ...
Meander Line and E-shape Antenna’s Parameters Enhancement For WLAN Applications
(2012)
The meander line antennas (MLA) are electrically small antennas that pose several performance related issues such as narrow bandwidth, low gain and high cross polarization levels. In this research enhancement techniques ...
(7,4) Hamming-like Code for QPSK Modulation
(2011)
Quadrature Phase Shift Keying (QPSK) is one of the most popular digital modulation techniques. It is widely used in existing technologies because of its spectral efficiency. In this paper, we present a (7, 4) code which ...
SIC detector for 4 relay distributed space-time block coding under quasi-synchronization
(IEEE, 2011)
Most research on Distributed Space Time Block Coding (D-STBC) assumes perfect synchronization between the relays' transmissions. In this paper, we propose a Sequential Interference Cancellation (SIC) approach for the ...
An Asymmetric Dual-band HTS Band-pass Filter for American Mobile Phone System
(2010)
The American Mobile Phone System (AMPS) has a very complex frequency allocation which is divided between two operators A and B. Therefore, high performance multiple-band system components are desired in both the downlink ...
Dual-band HTS filter using modified dual-spiral resonators
(IET Digital Library, 2010)
A symmetric dual-band filter with a centre frequency of 887 MHz is presented. The filter uses a modified structure of dual spiral resonators with interdigital capacitive load. At the same resonant frequency, the resonator ...
Design of multiple-band microwave filters using cascaded filter elements
(Taylor & Francis Group, 2009)
In this paper, a new approach to design multiple-band microwave filters is presented. A transfer function of a cascade of a low pass prototype filter with one or more band reject filters is calculated. This transfer function ...
