The First International Workshop on Software Radio Technology

作者： Zhijun Chen,Yafeng Zhan and Jianhua Lu department of Electronic Engineering,Tsinghua university,Beijing,{2.

Although Alternate Parallel Receiver(APRX)could effectively improve the maximum demodulating rate of the receiver,its frequency domain processing module consumes a large amount of multiplication units when the number of parallel input channels is large,making it unsuitable for use on FPGA software defined radio *** paper proposes an optimization scheme by introducing partitioned convolution and exploring the spectrum characteristic of the APRX input data,reducing the usage of multipliers greatly with no throughput *** the optimization,the number of real multipliers used in the frequency-domain processing module of the 16-ary APRX is reduced from about 576 to 68,with little performance *** optimized APRX is fairly suitable for FPGA software defined radio platform applications.

A generalized switched server（GSS） system is a discretely controlled continuous time system,which can be used for solving a class of task-balancing *** paper studies the switching policies for such GSS system,giving a focus on their balanceability,which answers the question that,under certain algebra constraint,whether the GSS system could be driven to reach the task-balancing status by the given switching *** switching policies,including FRR,FMM,and aMM policy,are first introduced,then the balanceability of the related switching policies is elaborated,and finally a sufficient condition for the balanceability of the FRR policy is obtained.
