Such formulation of power control is well-motivated in cellular PCS and UMTS, as both voice and streaming media require guaranteed short-term rates. A key difficulty is that the problem can easily become infeasible, implying that some link(s) must be dropped to accommodate the others. Since joint admission and power control is NP-hard, a host of heuristics have been proposed and implemented over the years, mostly based on the concept of gradual removals. More recently, the joint problem was revisited from a better-motivated Lagrangian relaxation / convex approximation viewpoint. In this contribution, we first derive a corresponding branch & bound algorithm that uses convex approximation for the bounding step. This can tackle moderate problem sizes, yielding optimal solution at much reduced average complexity relative to enumeration. Then, we propose a simple gradual admissions policy that appears promising. Simulations suggest that it can attain admission performance on a par with more complex methods, such as convex approximation, which are in turn known to outperform gradual removals.","PeriodicalId":436215,"journal":{"name":"2010 IEEE 11th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131142014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the objective to minimize the expected linear quadratic cost over a finite horizon, we propose a joint design of the sensor measurement quantization, channel error protection, and optimal controller actuation. It was shown in our previous work that despite this optimization problem is known to be hard in general, an iterative design procedure can be derived to obtain a local optimal solution. However, in the vector case, optimizing the encoder for a fixed controller is in general not practically feasible due to the curse of dimensionality. In this paper, we propose a novel approach that uses the approximate dynamic programming (ADP) to implement a computationally feasible encoder updating policy with promising performance. Especially, we introduce encoder updating rules adopting the rollout approach. Numerical experiments are carried out to demonstrate the performance obtained by employing the proposed iterative design procedure and to compare it with other relevant schemes.","PeriodicalId":436215,"journal":{"name":"2010 IEEE 11th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130595550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
