It is is capable of doubling the capacity without expanding the occupied frequency bandwidth in Radio Frequency (RF) signal processing based diversity scheme for Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems using 2×2 dimension antenna. This technique is great because the additional diversity can be gained(More)

This paper analyzes the performances of QPSK, GMSK and QAM modulation techniques using the GNU Radio software. These modulation techniques are used in most communications systems like cable modems, DSL modems, CDMA, 4G, Wi-Fi and WIMAX. A basic idea about Software Defined Radio (SDR) is also represented. SDR has the nature of modifying the system parameters(More)
Multiple Input Multiple Output (MIMO) systems based on single radio frequency (RF) receiver have been shown to achieve high data rates due to the exploitation of spatial diversity with the use of multiple antennas at the transmitters and/or receivers. However, exploiting the full multiplexing gain of the MIMO channel requires a RF front end and analog to(More)
