Abstract

In this paper, we propose a blind source extraction scheme in a bandwidth constrained wireless sensor network.We consider the extraction of multiple source signals in a sensing field. Each sensor observes a linear mixture of the source signals and their observations are corrupted by additive white Gaussian noise (AWGN). First a sensor in the network acts as a cluster head and performs local extraction of the source signals using a fast fixed-point algorithmbased on its own observation and the received noisy quantized data from other sensors. Then, the extracted signals are quantized using a pulse code modulation (PCM) method and the quantized data are sent to the sink in a multi-hop way through a fading channel. Finally the sink performs global extraction of the source signals using a constant modulus algorithm(CMA) and PCM decoding. In order to improve the accuracy of source extraction, a multi-cluster structure is also proposed. Simulation results confirm effective extraction of the source signals by comparing with the case of source extraction without quantization of the sensed data.
