    Analog and digital conversions in telecommunications are a fascinating topic for discussion. This paper will cover examples of special devices that have the ability to convert analog and digital signals. In analog technology, there are also advantages and disadvantages of amplitude modulation, frequency modulation, phase modulation, and quadrature amplitude modulation (QAM). This paper will give a brief description of those advantages and disadvantages, and also offer the specific modulation techniques that are used in a 56K modem, Asymmetrical Digital Subscriber Line, and Wi-Fi. The T(X) and the synchronous optical network (SONET) digital hierarchy will be further explained as well.…

    WLANS, personal communications services, and 2G digital cellular use the time division multiple access system. This system uses a combination of TDM and FDM. The numbers of channels using FDM is divided into the available or allocated frequency spectrum. The TDM is applied to carry the multiple users within each channel. Specific time slot for transmission are given to the users. At different moments in time, the users are speaking on the same frequencies. The advantages of this system are the increased capacity, spectral efficiency; the handsets have the capability to scan for a better performance.…

    Transmit Diversity

    • 7383 Words
    • 30 Pages

    So far we have investigated the use of antenna arrays in interference cancellation and for receive diversity. This final chapter takes a broad view of the use of antenna arrays in wireless communications. In particular, we will investigate the capacity of systems using multiple transmit and/or multiple receive antennas. This provides a fundamental limit on the data throughput in multipleinput multiple-output (MIMO) systems. We will also develop the use of transmit diversity, i.e., the use of multiple transmit antennas to achieve reliability (just as earlier we used multiple receive antennas to achieve reliability via receive diversity). The basis for receive diversity is that each element in the receive array receives an independent copy of the same signal. The probability that all signals are in deep fade simultaneously is then significantly reduced. In modelling a wireless communication system one can imagine that this capability would be very useful on transmit as well. This is especially true because, at least in the near term, the growth in wireless communications will be asymmetric internet traffic. A lot more data would be flowing from the base station to the mobile device that is, say, asking for a webpage, but is receiving all the multimedia in that webpage. Due to space considerations, it is more likely that the base station antenna comprises multiple elements while the mobile device has only one or two. In addition to providing diversity, intuitively having multiple transmit/receive antennas should allow us to transmit data faster, i.e., increase data throughput. The information theoretic analysis in this chapter will formalize this notion. We will also introduce a multiplexing scheme, transmitting multiple data streams to a single user with multiple transmit and receive antennas. This chapter is organized as follows. Section 2 then presents a theoretical analysis of the capacity of MIMO systems. The…
