Abstract
A simple low‐complexity algorithm is proposed for blind feedforward symbol timing estimation in time‐varying flat‐fading channels, assuming constant modulus signalling. Its important properties are brought out using asymptotic analysis. It is shown that at high Signal‐to‐Noise Ratios (SNRs), the algorithm results in a timing estimate with negligible bias. It also has a Mean‐Square‐Error (MSE) performance that is superior for short data records and small roll‐off factors to that of the Square‐Law‐(SQL‐) and the CycloStationarity‐(CS‐) based algorithms available to date. Computer simulations are presented to demonstrate effectiveness of the algorithm.
