In this paper we evaluate the dual stream multiple-input multiple-output (MIMO) performance for two rank adaptation schemes in 3GPP UTRAN long term evolution downlink. A capacity-based rank adaptation scheme as a transmission mode selection algorithm is compared to a throughput-based rank adaptation scheme by means of system level simulations run in four(More)
In this paper we analyze the link-to-system interface for MIMO-OFDM system level simulations and propose a computationally efficient method for calculation of the effective SINR. The accuracy of the proposed fast approximation of the effective SINR is evaluated both analytically with error bound estimation and by simulated BLER performance comparison. The(More)
at a public examination held at the lecture hall S1 of the school on 21st of September 2012 at 12 noon. Abstract Multi-antenna and multi-carrier wireless transmission techniques are expected to provide high peak data rates and spectral efႡciency, good coverage and reliable transmission required by emerging wireless standards such as 3GPP Long Term Evolution(More)
This paper presents a complete link level abstraction model for link quality estimation on the system level of filter bank multicarrier (FBMC)-based networks. The application of mean mutual information per coded bit (MMIB) approach is validated for the FBMC systems. The considered quality measure of the resource element for the FBMC transmission is the(More)
