Control of the project cost in the project implementation is mainly divided into bidding, contracting, construction and settlement. The following is the analysis and discussions of the author's experiences to the control of the project cost in the project implementation and the management measures.展开更多

Random projection code’s mapping matrix has significant influences on decoding performance as well as hardware implementation complexity. To reduce hardware implementation complexity, we design a quasi-cyclic mapping matrix for RPC codes. Compared with other construction approaches, our design gets rid of data filter component, thus reducing chip area 7284.95 um2, and power consumption 331.46 uW in 0.13 um fabrication. Our simulation results show that our method does not cause any performance loss and even gets 0.2 dB to 0.5 dB gain at BER 10-4.展开更多
