On some physical layer design aspects for machine type communication

With the development of current wireless systems, new type of communication is gaining a massive interest. It enables the communication of machines through a mobile network that is called machine type communication (MTC). Because of wide range of potential applications, MTC is a popular topic in research and industry area. It is important to develop technologies that support current MTC requirements and lead to near future technologies which are compatible with current MTC-like traffic. In this study, some physical layer design approaches for quantize and forward strategies are investigated to improve and support MTC in existing and near future small-cell networks. Results will be considered in terms of the tasks of macro base station and mini base stations. In addition, quantization effects on sum rate, equalization and soft demodulation are pointed out with these approaches.
