Spatial modulation for OFDM with linear constellation precoding

Direct application of spatial modulation (SM) for orthogonal frequency division multiplexing (OFDM) systems does not realize the inherent frequency diversity gain since information symbols are not spread over independently-faded subcarriers. This paper investigates a new transmission scheme that employs spatial modulation (SM) for each group of subcarriers in OFDM. Specifically, OFDM symbols in each group are passed through a precoder to maximize the diversity and coding gains, while spatial modulation is applied in each group to convey more information bits by antenna indices. Performance analysis and simulation results are carried out to demonstrate the superiority of the proposed scheme over a previously-proposed combination of SM and OFDM.

Giải pháp phát triển thị trường khách du lịch Trung Quốc của Hải Phòng, Quảng Ninh

Hiện nay du lịch ngày càng khẳng định vai trò quan trọng của mình và được coi là ngành kinh tế mũi nhọn của nhiều quốc gia. Nhiều chuyên gia đã dự báo tốc độ phát triển và khả năng lan tỏa của du lịch trong những năm sắp tới còn nhanh hơn cả ngành công nghệ thông tin. Trong xu thế hội nhập và phát triển chung đó, du lịch Hải Phòng và Quảng Ninh trong những năm qua đã có những bước phát triển đáng kể.

Social and ecological challenges of market-oriented shrimp farming in Vietnam

Vietnam is one of the largest shrimp exporters in the world. Since 2010, Vietnam has earned about two billion dollars annually through shrimp exports. As a fertile area of greatest potential for agricultural production in Vietnam, the Mekong Delta has been a major contributor to the country’s achievements, especially in the agricultural sector. During recent decades, trade liberation along with various policies in support of aquaculture has accelerated the development of shrimp production in the Delta. Based on an ethnographic study of shrimp farming in the Mekong Delta of Vietnam, I assert that along with great rewards arising from the expansion of shrimp farming areas, productivity, and export value, the shrimp industry has brought various environmental, economic and social challenges. Consequently, shrimp farming is a risky business and local inhabitants have relied on various strategies to cope with these challenges. Risk mitigation in shrimp production and labor migration are the...

Argumentation-based schema matching for multiple digital libraries

Title:  Argumentation-based schema matching for multiple digital libraries Authors:  Tho, Thanh Quan Luong, Xuan H. Nguyen, Thanh C. Keywords:  Digital library;Information retrieval;Argumentation;Schema matching Issue Date:  2015 Publisher:  EMERALD GROUP PUBLISHING LIMITED, HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Citation:  ISIKNOWLEDGE Abstract:  Purpose - Most digital libraries (DL) are now available online. They also provide the Z39.50 standard protocol which allows computer-based systems to effectively retrieve information stored in the DLs. The major difficulty lies in inconsistency between database schemas of multiple DLs. The purpose of this paper is to present a system known as Argumentation-based Digital Library Search (ADLSearch), which facilitates information retrieval across multiple DLs. Design/methodology/approach - The proposed approach is based on argumentation theory for schema matching reconc...
