Abstract

 In wireless communication, the receiver side BER strongly affected by channel noise, interference, distortion, synchronization error and wireless multipath fading chanel, and MIMO (Multiple-input and multipleoutput) is the use of antennas at both the end in wireless communication to improve BER performance. In this paper proposes a new NEA (embedding algorithm) for using digital watermarking image. The algorithm is performed for digital image as data. In the compared for NEA and well established Cox's modified embedding algorithm. A digital image watermarking are using discrete wavelet transforms and discrete cosine transforms. The Space-Time Block Coding with Multiple-Input Multiple-Output set-up for use in wireless fading channels. Comparison of diversity gain with MIMO systems in terms of BER for High QAM modulation scheme. The simulated using MATLAB and bit error rate (BER) performance is observed. The results has been shown in the paper for the simulation in various condition.
