The Channel Capacity of MIMO Systems with Impact of Transceiver Impairments and Varying Antenna Element
نویسندگان
چکیده
In this paper, an effort has been made to illustrate the performance of MIMO system under the effect of transceiver impairments on channel capacity with varying antenna element. The capacity of ideal MIMO channels depends upon number of antenna used in antenna array. At small SNR values capacity increases linearly. When there are distortions from physical transceiver impairments MIMO channels have a finite upper capacity limit, for any channel distribution and SNR. This work investigates the impact of inherent transceiver impairments of multiple-input multiple-output (MIMO) systems, channel Capacity saturates at high SNR but capacity can be enhanced by varying antenna elements.

An understanding of the interaction between the channel and the signal space is key to reliable communication. Multipath fading channels exhibit inherent diversity that can be exploited via appropriate signaling and reception.

متن کاملGeometric Modelling of a Spatially Correlated Mimo Fading Channel
For a single antenna channel, Shannon’s classical capacity formula predicts a capacity increase of approximately 1 bit/cycle for every 3 dB increase in signal to noise ratio (SNR). Consequently in multiple antenna arrays, with n antenna elements, the increase in capacity can be in the order of the number of antenna elements, n more bits/cycle for each 3dB increase in SNR. This tremendous gain i...
متن کاملAntenna Design and Channel Characterization for Mobile MIMO Systems
One significant difficulty associated with the implementation of multiple-input multiple-output (MIMO) technology is that communication node mobility leads to a time-varying channel which can limit the achievable system throughput [1]. This paper quantifies the degradation in channel capacity resulting from channel temporal variation using novel information theoretic metrics, and demonstrates t...
