Petri net is used widely to analyze and model various systems formally. Recently, Many Petri nets mania devote their efforts to enhancing and extending the expressive Power of Petri nets. One such effort is to extend Petri nets with object-oriented concepts. An object-oriented paradigm provides excellent concepts to model real-world problems.(More)
Expectations and requirements for wireless communication systems continue to grow rapidly. Reliability is one of the most challenging criterions. Soft combined turbo codes technique aims to improve the error correction capability of turbo codes by using soft combining principle, at bit level, inside the turbo decoder. In particular, this approach is based(More)
This paper presents a performance evaluation of OFDM LTE downlink physical layer according to the latest 3GPP specifications. Particularly, adaptive modulation and coding (AMC) is described and analyzed. This is in conjunction with the turbo decoding algorithm Max-Log-Maximum A Posteriori (Max-Log-MAP) used in soft input soft output (SISO) decoders. The(More)
