The Digital Video Broadcasting second generation (DVB – T2) system transmitter and receiver are to be implemented and simulated using MATLAB. The existing system uses the Multiple Input Single Output processing unit (MISO) technology as a means of transmission. The proposing system is the implementation of the DVB – T2 system with the support of multiple antenna transmission and multiple antenn...

It is well known that the employment of multiple antennas at both the transmitter and receiver increases the overall system capacity. This paper presents an overview of capacity variation in single-user and multiuser multiple-inputmultiple-output (MIMO) systems in Additive White Gaussian Noise (AWGN) and Rayleigh fading channels under the assumption that channel state information (CSI) is known...

We propose a Mutual Information (MI) based spatial frequency domain packet scheduling algorithm for uplink Orthogonal Frequency Division Multiple Access (OFDMA) multiuser multiple-input, multiple-output (MIMO) systems in this paper. The proposed scheduler is designed particularly for signal constellation constrained MIMO systems. The superiority of the investigated scheduler coupled with the in...

By adopting multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM) technologies, indoor wireless systems could reach data rates up to several hundreds of Mbits/s and achieve spectral efficiencies of several tens of bits/Hz/s, which are unattainable for conventional single-input single-output systems. The enhancements of data rate and spectral efficiency come...

Multicarrier transmission such as OFDM (orthogonal frequency división multiplexing) is an established technique for radio transmission systems and it can be considered as a promising approach for next generation wireless systems. However, in order to comply with the demand on increasing available data rates in particular in wireless technologies, systems with múltiple transmit and receive anten...

Multiple-input and multiple-output, or MIMO, is the use of multiple antennas at both the transmitter and receiver to improve communication performance. MIMO technology has attracted attention in wireless communications, because it offers significant increases in data throughput and link range without additional bandwidth or transmit power. In this paper, multiple-input–multiple-output (MIMO) sy...

Singular-value decomposition (SVD)-based multiple-input multiple-output (MIMO) systems have attracted a lot of attention in the wireless community. However, applying SVD to frequency-selective MIMO channels results in unequally weighted single-input single-output (SISO) channels requiring complex resource allocation techniques for optimizing the channel performance. Therefore, a different appro...

This paper investigates adaptive blind equalization for multiple-input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. The performance analysis of the CMA equalizer used in MIMO channels is first presented. Our analysis results indicate that for the MIMO FIR channels satisfying certain condition...

Increased data rates and reliability are the two key factors required to support emerging multimedia applications and new communications technologies. The two techniques used in high data rate transmission are orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) scheme. The OFDM is used to mitigate the problem of inter symbol interference (ISI) and provide...

Different interleavers are employed in Interleave Division Multiple Access (IDMA) instead of using different signatures as in a conventional code-division multiple-access (CDMA) scheme. Multiple Input Multiple Output (MIMO) system exploits multiple antennas at transmitter and receiver to mitigate the fading effect. To offer the promising communication beyond 3G and 4G wireless communication, ID...
