Double Allocation of Spreading Code Minimizing SI and PAPR for LP-OFDM UWB System
Self-interference (SI) occurs if the transmission is through a multipath channel. The channel distorts helps to break the orthogonality between the spreading codes. In addition, the amplitude of linear precoded orthogonal frequency division multiplexing (LP-OFDM). LP-OFDM signals have strong fluctuations. Thus, it is necessary to seek or to minimize these two problems by the reduction of term S...
متن کاملsimulation and design of electronic processing circuit for restaurants e-procurement system
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
15 صفحه اولAdaptive Selection of Spreading Code Subsets from Orthogonal Binary Code Sets for Reduced PAPR in MC-CDMA Systems
One of the major concerns with multicarrier CDMA (MC-CDMA) systems is the high peak to average power ratio (PAPR) that can lead to degraded transmission power efficiency. Based on the well known fact that suitable allocation of user spreading codes can be used as a PAPR reduction tool, we in this contribution, investigate the PAPR property of a recently proposed spreading code set called “Ortho...
متن کاملUnifiable scheduling and allocation for minimizing system cycle time
This paper describes a new scheduling and allocation algorithm which optimizes a datapath-controller system for clock cycle time. The cycle time of a VLSI system depends not only on the characteristics of the datapath and controller in isolation but also on the interactions between them. A datapath may impose both arrival time constraints on controller inputs and departure time constraints on c...
متن کاملLarge Code Set for Double User Capacity and Low PAPR Level in Multicarrier Systems
SUMMARY In this paper, a new large spreading code set with a uniform low cross-correlation is proposed. The proposed code set is capable of (1) increasing the number of assigned user (capacity) in a multicarrier code division multiple access (MC-CDMA) system and (2) reducing the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) system. In this paper, we ...
