Distributed estimation in sensor networks with repetition coding
Li Zhang, Tao Cui, Xian‐Da Zhang · Tsinghua Science & Technology · 2011
This paper considers the distributed estimation of a source parameter using quantized sensor observations in a wireless sensor network with noisy channels. Repetition codes are used to transmit quantization bits of sensor observations and a quasi best linear unbiased estimate is constructed to estimate the source parameter. Simulations show that the estimation scheme achieves a better power and spectral efficiency than the previous scheme.
