摘要：
Investigation in MIMO-RSN (Multi-input Multi-output radar sensor networks) is becoming more attractive in current literature. In a MIMO system, power allocation in accordance with the channel gain can significantly improve the system throughput performance. This paper investigates three power allocation methods in MIMO-RSN: water-filling, equal power and channel inversion. Their performances are analyzed in terms of target detection probability, false alarm rate, and amount of information for flat fading channels. Baker code is applied in the transmitting signal with different power control schemes to improve the target detection performance. The simulation results show that the water-filling in MIMO-RSN achieves the best detection performance while the channel inversion gets the worst.
