Performance Analysis of OFDM Polarization Receive Diversity System in Correlated Ricean Fading Channels

چکیده
In this paper a complete analytical model for BER (Bit Error Rate) calculation of OFDM (Orthogonal Frequency Division Multiplexing) system with polarization diversity is presented. The assumed system consists of one transmit and dual polarized receive antenna. Propagation environment is characterized with Ricean fading and novel method for analytical determination of the system BER performance is introduced. Maximal ratio combining of the received diversity signals is performed on subcarrier basis. The obtained analytical results are compared with the ones attained by simulation. It is shown that polarization diversity scheme can be considered as an efficient solution for improving OFDM system performance.

Capacity-Maximization Based Variable Per-Tone Joint Transmit/Receive Antenna Selection for IEEE802.11n MIMO-OFDM Spatial-Multiplexing WLANs over Spatially-Correlated Ricean-Fading Channels
This paper focuses on capacity-maximization-based joint transmit/receive antenna selection scheme in IEEE 802.11n MIMO-OFDM WLANs with antenna arrays of higher-order modal SMP-SCP-ULA over spatially-correlated Ricean fading channels. As the selection signalling is perfectly fed back to transmitter we propose joint antenna selection and we use a flexible Two-Step Selection Algorithm (TSSA) at re...

This paper studies the performance of switch and stay combining (SSC) diversity receivers operating over correlated Ricean fading satellite channels. Using an infinite series representation for the bivariate Ricean probability density function (PDF), the PDF of the SSC output signal-to-noise ratio (SNR) is derived. Capitalizing on this PDF, analytical expressions for the corresponding cumulativ...

This paper studies performance of two-hop relay system operating in Ricean fading environment. Implementation of a dual-polarized antenna at the receiver node is assumed, as a solution for enhancing the system energy efficiency. First, we analytically examine the level of performance improvement for decode-and-forward (DF) relay systems, in terms of bit error rate (BER), accomplished just by ca...

In this paper, we provide a unified analysis of average symbol error probability (SEP) for a diversity system over generalized gamma fading channels, which is a generalization of Rayleigh, Nakagami, and Ricean fading channels. We consider independent generalized gamma fading on the diversity branches and derive different closed-form expressions of the average SEP for a general class of M -ary m...

Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
