A Software-configurable Adaptive Array Antenna System for ISDB-T Reception

摘要

This paper presents an adaptive array antenna system for ISDB-T reception (Japan Digital TV Broadcasting) with the adaptive array algorithm is configurable by software. By exploiting the merits of Software-Defined Radio (SDR), a number of adaptive algorithms such as digital beam-forming and/or null-steering (i.e. Maximum Ratio Combining -MRC, Sample Matrix Inversion -SMI) are embedded in DSP board that is reconfigurable according to the radio propagation environment. The experiment results for MRC and SMI algorithms successfully improved BER performance for ISDB-T reception with an analog TV interference and inter-symbol interference by Over GI delay waves.
