Abstract - The talk focusses on building/ renewing interests in chaotic maps to solve some of the critical problems in communication and signal processing. Chaotic maps can be considered as complex non-linear, initial condition dependent mathematical functions with very interesting features. The talk throws light on a subset of diverse applications from modeling atrial fibrillation from electrocardiogram (ECG) time series to lowering peak to average power ratio (PAPR) in orthogonal frequency domain multiplexing (OFDM) systems, using a known repository of chaotic functions. The underlying engineering challenge is, how can we leverage these properties to solve, model, analyze and predict future values of seemingly random behavior of highly dynamical systems using chaotic maps.
