Book Description
The demand of different multimedia services and different internet supported applications on mobile devices requires a high speed data rate and good service of quality. This can be obtained by implementing multiple Antenna technology on both stations i.e. User terminal and base station with an appropriate coding technique, and on the other hand MIMO can fulfill 3G & 4G demand and standard with a combination of other techniques. The system's error performance is analyzed through simulation which showed the simulated results of Multi-Rate Resource Control (MRRC) scheme and Alamouti scheme are identical. And also the Bit Error Rate (BER) were checked for different MIMO systems. By improving the BER, we will get the better QoS.

BER Performance Analysis and PAPR Mitigation in MIMO OFDM Systems

Category : Technology & Engineering
Languages : en
Pages : 0
Book Description
Wireless communications is expected to provide users with wireless multimedia services like high speed internet access, wireless television and mobile computing. These services are providing the communication technology with high data rates, higher carrier frequencies and mobility which enables reliable transmissions over mobile radio channels gaining much growth demand. OFDM system will be effective means of communication if this orthogonality of carrier signals are maintained properly. Modulation is the process of mapping the data onto the carrier signal amplitude or phase. Transmitting a baseband signal over a long distance is highly impossible due to loss of signal strength. MIMO systems can get better the capacity by only using few minimum number of transmit or receive antennas when compared to single input single output systems in flat fading channels. Fourth generation MIMO- OFDM systems has capacity, exposure and dependability higher over multipath fading channels.

Performance Analysis of Adaptive Interleaving for MIMO-OFDM Systems

Pages : 5
Book Description
In this paper, an adaptive interleaving scheme for multiple-input and multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems is proposed. The scheme could better exploit the instantaneous channel variation by rearranging the transmitted symbols according to the quasi-instantaneous channel SNR of the OFDM frame. The purpose is to break up a long burst channel error so that overall bit error probability is reduced. The upper bound of pairwise error probability (PEB) of the MIMO-OFDM systems is investigated. The code gain and diversity gain of the proposed scheme are given. The result shows that the major factor affecting performance of the proposed scheme is SNR, channel order and the number of receive antenna. Extensive simulations show that significant SNR can be obtained with the proposed scheme and the MIMO-OFDM case has a performance improvement over the single antenna case. Compared with block interleaving, for 2Tx- 2Rx case at a BER of 10 (exp -2), adaptive interleaving offers a 5dB improvement.
