Wavelets have been widely used in digital wireless communication systems, including data compression, source and channel coding, signal denoising, channel modeling, and transceiver design. Wavelets' primary advantage in these applications is its flexibility and ability to properly describe signals. Recent trends and advances in the usage of wavelets in wireless communications are discussed in this article. Wavelets are used in wireless channel modeling, interference reduction, denoising, OFDM modulation, multiple access, Ultra Wideband communications, cognitive radio, and wireless networks, among other applications. The convergence of information and communication technologies, as well as the potential of ubiquitous connectivity, has made creating systems and architectures capable of processing huge quantities of data under severe resource limitations like as power and bandwidth difficult. Wavelets are particularly suited to tackle this problem. Wavelet technology is a good contender for future wireless communication because of its versatility and adaptability.
