Carrier Offset and Channel Estimation for Cooperative MIMO Sensor Networks

Carrier Offset and Channel Estimation for Cooperative MIMO Sensor Networks
— A cooperative MIMO network is considered with Ns sensors and a collector node with Mc antennas. In a practical implementation of this network, the sensor carriers have relative frequency offsets which must be estimated along with the MIMO channel. Generalized successive interference cancellation (GSIC) is proposed for this joint estimation problem. The primary operations in GSIC are correlation, FFT and cancellation. A reconfigurable hardware (FPGA) implementation of these GSIC primitives is described. A hybrid analysis/simulation for symbol error probability (SER) is presented with results for GSIC using Alamouti and G4 c codes.
