Abstract

A software defined radio (SDR) system is used to reconfigure all or many specifications such as modulation scheme, demodulation, coding etc. Therefore, supplementary information allow recognition of these specifications by the receiver is required. Since much redundant supplementary information reduces efficiency in transmission, we have aimed to carry out blind adaptive demodulation which, can adaptively demodulate without supplementary information. This paper proposes and investigates both a blind adaptive algorithm for estimating channel and that for estimating a modulation scheme. Computer simulation evaluates the proposed blind estimation algorithm
