Abstract
The invention presents an intelligent deployment cascade control (IDCC) device for frequency division duplexing (FDD)-orthogonal frequency division multiplexing access (OFDMA) indoor small cell to enable easy installation, multi-user (MU)service reliability, optimum throughput, power saving, minimum interference and good cell coverage. The proposed IDCC device is designed with a cascade architecture, which mainly contains five units including a resource allocator, a minimum throughput/cell edge CQI converter, an adaptive neural fuzzy inference system (ANFIS) based initial transmit power setting controller (ITPSC) in the first cascade unit, an ANFIS based channel quality index (CQI) decision controller (CQIDC) in the second cascade unit and an ANFIS based self-optimization power controller (SOPC) in the third cascade unit. The SOPC consists of three parts, namely the transmit power adjustment estimator (TPAE), transmission power assignment and self-optimization power controller protection mechanism.
