Image maximum fusion algorithm based on wavelet transform;

Lower bound on BER performance for maximal ratio combining with weighting errors;

New efficient methods for performance analysis of maximal ratio combining diversity receivers;

A simulation model of maximal ratio combining in correlated rayleigh fading channels was established, and bit-error performances of maximal ratio combining in correlated Rayleigh fading channels were investigated theoretically.

The authors briefly introduced the definition and characteristic of spatial diversity,and presented a detailed description of transmit diversity which employed STBC,and received diversity which employed MRC,compared the different impact of the two methods on improving the throughput of OFDM based WLANs through simulation.

This paper focuses on the influence of quantization noise in MRC combining in Rayleigh Flat-fading channel.

Conventional Maximum Ratio Combining(MRC) using conjugate of channel estimation is considered the optimal combining scheme when fading parameters can be perfectly tracked and different diversity branches have equal noise power.

In this paper,the formulas of sliding window channel estimation algorithm with maximum ratio combining are given in DS-UWB system.

Meanwhile,the maximum ratio combining(MRC) method was introduced to improve the proposed scheme,and decrease the computational complexity further.

In this paper,the performance of a scheme of combining transmit antenna selection and maximal-ratio combining(TAS/MRC) is studied for the case of spatial receive correlation.

Exact closed-form expressions of the average symbol-error rate(SER) for M-ary phase shift-keying(MPSK) and M-ary differential phase-shift-keying(MDPSK) with maximal-ratio combining(MRC) diversity scheme in correlated Nakagamim fading channels have been obtained.
