| Summary |
In densely deployed wireless sensor networks, sensor observations
are spatially correlated. Furthermore, the nature
of physical phenomena constitutes a temporal correlation
between transmitted observations of an individual sensor
node. In this paper, we propose a joint iterative channel
decoding scheme using turbo codes. The proposed decoder
exploits the spatial and temporal correlations of two binary
data sequences to achieve additional coding gain. Simultaneously
exploiting the spatial and temporal correlation, the
proposed decoder achieves large performance gain. |
