    Ofdm based scm for multicast dual amplify and forward relays
    (2015) Muhammad Adnan; Irfan Ahmed; Ishtiaq Ahmed; Chen, Shaohua; Wang, Yafeng; Yang, DaCheng
    In multihop OFDM relay systems the end-to-end throughput can be increased by incorporating subchannel mapping (SCM) at the relay nodes. This helps in achieving high data rate requirements for live streaming applications. Average Symbol Error Probability (SEP) is an important measurement for investigating wireless communication systems. This paper presents the statistical and symbol error performance analysis of the 2-hop OFDM based multicast strategy with Amplify and Forward protocol and subchannel mapping scheme. Closed Form expressions for probability density function (PDF) and well-approximated symbol error probability of the signal to noise ratio (SNR) for the kth mapped subchannel pair link are provided

    RPD management system
    (UMT Lahore, 2015) Irfan Ahmed; Usman Arshad; Maroof Subhani
    This is an “RPD management system.” The term “RPD” stands for retail, point of sale, and distribution. The conventional methods involved a lot of work by an individual, which cost time and money. Therefore, the idea is to automate the system so that it can manage the entire transactional procedures with minimum cost and maximum efficiency. The software comprises three major areas of operations: Retail Point of sale Distribution
