Subband Array Implementations for Space-Time Adaptive Processing
Intersymbol interference (ISI) and cochannel interference (CCI) are two primary sources of signal impairment in mobile communications. In order to suppress both ISI and CCI, space-time adaptive processing (STAP) has been shown to be effective in performing spatio-temporal equalization, leading to increased communication capacity as well as improved quality of service. The high complexity and sl...
متن کاملSubband Adaptive Array for Space-Time Block Coding
Future mobile communications is required to provide data transmission with higher rates and more reliability than current systems. As a solution to this problem, the diversity transmission using Alamouti’s space time block coding (STBC)[1] has been adopted in several wireless standard due to its attractive features such as full spatial diversity at full transmission rate. Usually, it requires c...
متن کاملSubband Realization of Space-Time Adaptive Processing for Mobile Communications
In this paper, we study the space-time adaptive processing (STAP) and its subband realization for mobile communications. The conditions of perfect STAP processing (i.e., perfect equalization of desired user signal and perfect suppression of undesired user signals), are investigated in noise-free case, which provide a basic rule for practical design of STAP systems. Based on the polyphase repres...
متن کاملSubband Space-Time Adaptive Processing for Mobile Communications
Abstract This paper proposes the scheme of subband spacetime adaptive processing (SSTAP) for mobile communications. Unlike the available array processing methods, this scheme combines the advantages of the space-time adaptive processing (STAP) and the subband signal processing. It is known that the main difficulties for the real-time implementation of STAP are due to its huge computation burden...
متن کاملDesign of Antenna Array Configurations for Space-Time Adaptive Processing
It is known that the output performance of a conventional adaptive antenna system is greatly influenced by its antenna array configuration. Such a conclusion holds true to space-time adaptive processing (STAP) systems of mobile communications, where receiving signals consist of the superimposed multipath rays with delay spread and angle spread. It is considered that the associated system perfor...
