Low-density parity-check (LDPC) codes with turbo-decoding message-passing (TDMP) scheduling can obtain good performance and high convergence rates. In addition, the min–sum (MS) algorithm can reduce the complexity. The hybrid normalized MS algorithm with TDMP scheduling is presented to achieve good performance and to lower the complexity. For a quasi-cyclic LDPC (QC-LDPC) code with a long code length,...
Cognitive wireless network is one of efficient wireless transmission methods to solve today's wireless network problems like a lack of wireless radio resource or congestion of wireless bands. However, Cognitive wireless network still has some problems to realize like efficient algorisms, control methods, and technical problems to attain efficient transmission. In this paper, the Min-Max based AHP...
In case of emergent situation like taking patient in an ambulance, it is important to send essential information by verious environments like the condition of patients or delivery time for hospital. In this paper, Cognitive Wireless Network by Transitional AHP based on Emergency Policy is proposed. The proposal system is expected with cognitive wireless network consisted with multi wireless link and...
Fractional frequency reuse (FFR) is often used in interference-limited systems to improve coverage in cellular networks. Its cost is reducing the amount of available resources. In this paper, we intend to propose the FFR scheme by introducing the concept of normalized spectral efficiency (nSE). With the optimal frequency reuse factor (FRF), the FFR scheme can maximize the system SE with throughput...
