The combination of Log MAP and SOVA avoids updating the matrices of the maximum path, and also makes a contribution to the requirement of short delay. The simulation results of several SCCCs show that the improved decoder can obtain satisfied performance with short frame interleaver and it is suitable to the high bit rate low delay communication systems.展开更多

The acts of violence; on the other hand, can be defined as the practices pertaining to intimidating, terrorizing and even tyrannizing human beings. There is a widespread agreement on the idea that a healthy and balanced society necessitates the conscious contribution of each member to the solution of social, economic and cultural problems. Undoubtedly, the mass media, particularly TV, plays a significant role in this process. In the same way, the media content considerably accelerates the respective learning process through news, advertisements and particularly TV serials. The primary purpose of this study is to determine the types and ratios of violence displayed in popular Turkish TV serials with respect to the total airing time. Thus, three popular TV serials with the highest rating were determined as the corpus of this study. Then, every sixth episode of each serial in a 36-week-season was chosen as the sampling. With this idea in mind, the sequences displaying violence in the respective serials were measured with content analysis method and classified according to the types of violence. Thus, ratios for each type of violence were found out and shown on graphs. It is expected that the findings will provide a basis for a further study in which a comparison between the escalation of violence in Turkish society and the ratio of violence demonstrated in popular TV serials can be made.展开更多

On-Chip SerDes Transceiver is a promising solution which can reduce the number of interconnects and offers remarkable benefits in context with power consumption, area congestion and crosstalk. This paper reports a design of a new Serializer and Deserializer architecture for basic functional operations of serialization and deserialization used in On-Chip SerDes Transceiver. This architecture employs a design technique which samples input on both edges of clock. The main advantage of this technique which is input is sampled with lower clock (half the original rate) and is distributed for the same functional throughput, which results in power savings in the clock distribution network. This proposed Serializer and Deserializer architecture is designed using UMC 180 nm CMOS technology and simulation is done using Cadence Spectre simulator with a supply voltage of 1.8 V. The present design is compared with the earlier published similar works and improvements are obtained in terms of power consumption and area as shown in Tables 1-3 respectively. This design also helps the designer for solving crosstalk issues.展开更多
