Abstract
Continuous phase frequency shift keying (CPFSK) has been widely used in wireless communications, as its continuous phase and constant envelop lead to high bandwidth and power efficiency. In non-cooperative communication systems, the CPFSK parameters such as modulation index, pulse shape and pulse length are unknown to the receiver and need to be estimated. This is a challenging task especially when the transmission is bursty. In this paper, long short term memory (LSTM) neural networks are proposed to tackle this problem. Specifically, three LSTM networks with identical structure but trained separately are used to estimate three important CPFSK parameters (modulation index h, pulse length L and pulse shape q(t)) in parallel. Simulation results show that by suitably preprocessing the input data before the LSTM network, the proposed blind estimation scheme is able achieve high estimation accuracy of more than 95% in most cases.
