— Multiple Input Multiple Output (MIMO) systems have recently emerged as a key technology in wireless communication systems for increasing both data rates and system performance. There are many schemes that can be applied to MIMO systems such as space time block codes, space time trellis codes, and the Vertical Bell Labs Space-Time Architecture (V-BLAST).(More)
This paper proposes a novel signal scheme called " Hybrid BLAST STBC approach " this combines MIMO (multiple-input multiple-output) and STBC (space time block code) to generate a system functionally superior to MIMO and STBC systems. This paper compares and investigates the capacity of high data rate wireless local area network systems using MIMO(More)
Today is the world of most scientific and advanced level of dyeing. There are huge numbers of process to do coloration. Natural and man-made colors are also used. In this research, the difference of garments dyeing and fabric dyeing are analyzed. At first we compare garments dyeing and fabric dyeing process with using respectively direct dye and reactive(More)
The MIMO (multiple-input multiple-output) systems have gained popularity and attracted attention of late for their ability to enhance all areas of system performance. Inspired by the success of MIMO systems in communications, several publications have advocated the concept of new MIMO emerging active sensing radar technology from the system implementation(More)
The realization of wireless communication providing high speed, high capacity and high quality information exchange between two portable terminals that might be located anywhere in the world is still the communication challenge. For the development of future wireless communication systems, an extremely spectrum-efficient transmission technology is required.(More)
