Abstract


3G wireless communication system capable of providing people with high-speed wireless transmission capability , and better quality of business experience , and richer content , so that communication becomes more rapid , pluralism , universal . TD-SCDMA system with independent intellectual property rights , China has proposed 3G mobile communication system access standards . Said in order to support high-speed data business , TD-SCDMA has proposed HSDPA and HSUPA two , enhanced standard , available in single-frequency point 1.6MHz bandwidth , provide 2.2Mbps and 2.8Mbps uplink and downlink peak rate of air interface . HSDPA and HSUPA have completed an agreement on standardization work has been put into production and testing aspects of product design . In this thesis, both from resource scheduling and power control and authorization HSUPA base station end of algorithm design and simulation analysis . First , the design of the scheduling algorithm from close to the protocol point of departure , the actual system can be obtained in the protocol parameters for the calculation of the formula and deduced . The different scheduling algorithm, will be a different scheduling factor combination . For a conventional scheduling algorithm , MaxSINR , PF, RR text will be given of a suitable way to achieve TD-HSUPA . The scheduling factor in accordance with its physical meaning embodied classification , and into the quantization levels and throughput . Simulation proved the algorithm characteristics to achieve full compliance with the properties of the algorithm , and the performance of the system is given . Secondly, the power control and authorization aspects , combined with TD-HSUPA uplink characteristics and resource allocation often appear first elaborated the inner loop power control and outer loop power control algorithm , and propose two different power authorization algorithm . Both power authorization algorithm in the system throughput , UE throughput , interference level have their own advantages . Two algorithms in the TD system commonly used in high - speed business TDM resource configuration mode simulation , through comparative analysis , the results showed that levels of throughput and interference exists between the two algorithms compromise . That by sacrificing certain cell throughput , can be exchanged for the upgrading of the level of interference and edge user performance . For the contents of this article , you can further study and refinement , the study combines QoS scheduling algorithm and combined with the power of interference coordination authorized as Next TD-HSUPA base station algorithm optimization direction .
