Channel Estimation for Physical Layer Network Coding Systems

By: Feifei Gao,Chengwen Xing,Gongpu Wang

This SpringerBrief presents channel estimation strategies for the physical later network coding (PLNC) systems. Along with a review of PLNC architectures, this brief examines new challenges brought by the special structure of bi-directional two-hop transmissions that are different from the traditional point-to-point systems and unidirectional relay systems. The authors discuss the channel estimation strategies over typical fading scenarios, including frequency flat fading, frequency selective fading and time selective fading, as well as future research directions. Chapters explore the performance of the channel estimation strategy and optimal structure of training sequences for each scenario. Besides the analysis of channel estimation strategies, the book also points out the necessity of revisiting other signal processing issues for the PLNC system. Channel Estimation of Physical Layer Network Coding Systems is a valuable resource for researchers and professionals working in wireless communications and networks. Advanced-level students studying computer science and electrical engineering will also find the content helpful.

Nanking 1937

Memory and Healing

By: Robert Sabella,Feifei Li,David Liu

In recent years the international community has begun to scrutinize and, in many cases, condemn the atrocities that took place at Nanking in late 1937. This is all part of a larger worldwide movement in which both nations and multinational groups are attempting to reach closure regarding past atrocities and inhumanities. As represented by the contributors to this book, these activities have an importance reaching far beyond aggressors or victims, beyond admission or vindication, but rather are a search for the common causes of all human atrocities and for solutions that would set humanity on a path toward a more peaceful and harmonious international community.

Living Conditions and Targeted Aiding Mechanisms of the Urban Underclass in China

By: Zhu Li,Mao Feifei

Based on the approaches of questionnaire and interview, this book studies the urban subalterns formed with a considerable scale in China since the 1990s. By investigating their living status in detail, it depicts the mental conditions, class consciousness, migration, living difficulties and dilemmas of the subaltern class. It’s worth noting that in addition to the group at the bottom of the economic pyramid, this book expands the definition of subaltern by including the deviant underclass. Then it examines the factors causing the living dilemmas and provides suggestions aiming to mitigate them from the perspective of social succor. In the last chapter, this book focuses on the theoretical discussions on subaltern studies. New concepts such as the deviant subaltern group and social vigilance are created, and new theories such as production and transmission mechanism of the subaltern group are put forward.

A Comparative Study of Wh-Words in Chinese Efl Textbooks, Elicited Native and Non-Native Speaker Data and Written Native and Non-Native Speaker Corpora

A Thesis Submitted to the Graduate School of Humanities of the University of Birmingham for the Degree of Doctor of Philosopy

By: Feifei Zhang

This study presents a corpus-based analysis of the use of wh sentences by language learners, in language textbooks and in authentic written discourse. It focuses on the polysemeous nature of wh words, which can be used as interrogatives, declaratives and to introduce subordinate clauses. The analysis of wh sentences in EFL textbooks showed that there are more prototypical examples at low proficiency levels. When teaching the interrogative, textbooks focus almost exclusively on grammatical words, particularly at the beginners level. The analysis of wh sentences elicited from Chinese speaking learners of English and Expert users of English suggested that the prototypical structure is very strong in both sets of data, although native speakers tend to use more prefabricated chunks of language. The analysis of wh sentences from native speakers and non-native speakers written corpora suggested that subordinate clauses are strongly present in both corpora, except for the word why in non-native speakers data. The use of different words occurring immediately after wh words in the two corpora can be explained by (1) the relatively small vocabulary size of the L2 speakers; (2) non-native speakers lack of awareness of restricted collocations; (3) L1 transfer; (4) over/under-generalization of rules and (5) textbooks.
