  author={Jide Julius Popoola and M. Eng},
In today’s knowledge-based world, wireless communication plays an important role in economic growth and well-being of people. However, because of the undesirable effects of fading on wireless channel, the information transmission is being impaired. Hence, in order to achieve reliable and effective information transfer, an effective means of reducing the fading effect on wireless channel must be found. Diversity scheme has been observed as an effective means of mitigating the effect of fading… 

Performance Analysis of Bit-Error-Rate and Channel Capacity of MIMO Communication Systems over Multipath Fading Channels

In wireless communication systems (WCS), channel characteristics are random and unpredictable. The resultant effect of the randomness is the multipath effect that leads to multipath fading. Multipath

Link Adaptation for Microwave Link using both MATLAB and Path-Loss Tool

The results show that, employment of link adaptation scheme offers better performance regarding the system availability and SE.

Fading Mitigation Techniques in Wireless Mobile Communication Systems

In wireless telecommunications, multipath is the propagation phenomenon that results in radio signals reaching the receiving antenna by two or more paths. Causes of multipath include atmospheric

Effective Fading Reduction Techniques in Wireless Communication System

Different techniques being employed to reduce the effect of fading using Diversity, rake receiver and equalization are also discussed.



On Limits of Wireless Communications in a Fading Environment when Using Multiple Antennas

Some basic information theory results that promise great advantages of using MEAs in wireless LANs and building to building wireless communication links are presented and standard approaches such as selection and optimum combining are seen to be deficient when compared to what will ultimately be possible.

Results show that with optimum linear processing at the receiver, up to M/2 channels can be established with approximately the same maximum data rate as a single channel with the potential for large capacity in systems with limited bandwidth.

Unified analysis of switched diversity systems in independent and correlated fading channels

The moment generating function (MGF) of the signal power at the output of dual-branch switch-and-stay selection diversity (SSD) combiners is derived. The first-order derivative of the MGF with

Diversity performance of DS-CDMA communication system on Nakagami fading with arbitrary parameters

Exact analysis of postdetection combining for DPSK and NFSK systems over arbitrarily correlated Nakagami channels

This work directly determines the error probability from the characteristic function of decision variables, resulting in closed-form solutions involving matrix differentiation in postdetection combining systems in an arbitrarily correlated Nakagami environment.

MRC performance for binary signals in Nakagami fading with general branch correlation

The new formulation presented for the bit error rate, in which the covariance matrix of the fading at the L branches explicitly appears, allows arbitrary branch correlation to be taken into account for any diversity order in the case of identical fading severity on the branches.

Simplified processing for high spectral efficiency wireless communication employing multi-element arrays

It is shown that robust wireless communication in high-scattering propagation environments using multi-element antenna arrays (MEAs) at both transmit and receive sites using a simplified, but highly spectrally efficient space-time communication processing method can offer no more than about 40% more capacity than the simple architecture presented.

Transmit diversity over quasi-static fading channels using multiple antennas and random signal mapping

A new scheme is introduced that achieves a diversity gain for coded systems under static fading conditions by using multiple antennas and random signal mapping and results show that N/spl ap/8 is enough to achieve close to the performance of a perfectly interleaved system.

The error rate performance of coherent M-ary phase shift keyed signals in slow nonselective Nakagami fading and additive white Gaussian noise channel is analysed. For real values of the Nakagami
