Description: In this paper, we propose a novel multi-code turbo decoder
architecture for 4G wireless systems. To support various
4G standards, a configurable multi-mode MAP (maximum
a posteriori) decoder is designed for both binary
and duo-binary turbo codes with small resource overhead
(less than 10 ) compared to the single-mode architecture.
To achieve high data rates in 4G, we present a parallel
turbo decoder architecture with scalable parallelism tailored
to the given throughput requirements.

Description: Ajey, S., B. Srivalli, et al. (2010). On performance of MIMO-OFDM based LTE systems. Wireless Communication and Sensor Computing, 2010. ICWCSC 2010. International Conference on.
4G wireless systems predominately employ multiple input multiple output (MIMO) with an orthogonal frequency division multiplexing (OFDM) system. Like other 4G systems long term evolution (LTE) also employs MIMO-OFDM physical layer. MIMO helps in increasing the throughput whereas OFDM converts a frequency selective fading channel to multiple flat fading sub-channels facilitating easy equalization. It is proposed that LTE system should mandatorily support 2Ã — 2 MIMO setup. Our paper focuses on the performance of such a LTE system with two transmit antennas and two receive antennas in a frequency selective fading environment.

The challenge in such multiuser systems is designing transmit vectors while considering the co-channel interference of other users. Typical optimization problems of interest include the capacity problem - maximizing the sum information

Description: we present a practical link adaptation
algorithm for MIMO-OFDM systems. The proposed solution is
based on sounding the channel periodically and choosing the
optimal mode that will maximize the throughput or energy
efficiency (EE) while satisfying the application’s quality of service
(QoS) requirements. In addition, we address practical problems
such as the computational complexity of the algorithm and
determination of sounding period by novel closed form solutions
and iterative algorithms. Realistic link level simulations confirm
that the proposed solution achieves significant improvement
over existing link adaptation algorithms when the aim is to
maximize the throughput, and provides orders of magnitude
gain in energy efficiency compared to poorly chosen fixed modes
when used for energy efficiency maximization purposes. The
resulting algorithms are implemented on a real time MIMOOFDM testbed, and we report on the experimental results.

Description: Repeater communication is one promising candidate solution in future cellular networks because of its ability to increase throughput, data rate and coverage. It is also considered as one candidate technology feature in 3GPP/LTE-A. Traditionally repeaters have been active continuously and perform blind forwarding without knowing the signal. However the repeater in LTE Advanced is likely to include some advanced functionalities such as frequency selectivity, gain controllability, multi antenna ability, advanced antenna processing, optimum power control algorithm, etc.

Description: With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication, the role of MIMO detectors plays an important part to remove inter-symbol interference (ISI) caused by multipath fading channel. In this paper the BER performance of IEEE 802.11n for 3x2, 4x2 and 4x3 antennas are compared using MMSE and ZF detectors in Matlab Simulink.
