Abstract: Communication over wireless channels is faced with bandwidth and power limitation. Propagation over these channels is filled with challenges like fading, Inter symbol and Co-Channel interference. Fading is moderated by channel coding, Interleaving and antenna diversity techniques. Frequency, Time and Space are some of the diversity schemes used in antenna transmission and reception process. The paper presents a brief introduction on diversity fading mitigation techniques and introduces a new novel diversity scheme based on wavelet transforms: Space wavelet, Time wavelet, and Frequency wavelet diversity.
Keywords: Wavelet, Diversity, Fading, Rayleigh Channel.
Scope of the Article: Microwave Antenna
