Hence computer simulations have gained global acceptance as a method to evaluate system performance.
The intention of this chapter is to make the designer aware of the multiple computer
simulation techniques available. The chapter starts with the well-known Monte Carlo technique making
no assumptions about the noise statistics, but having the caveat of long runtime. Various methods
are introduced to reduce the simulation runtime, such as importance sampling, improved
importance sampling, and tail extrapolation. Lastly, a semi-analytic approach is provided to offer the
fastest computer simulation runtime benefit.
Chapter 9 provides insight into numerous topics such as orthogonal frequency-division multiplexing
(OFDM) and the usage of such for third-generation long-term evolution (3G LTE) and
Mobile TV. A discussion of delivering broadcasting services through the broadcast and multicast
channels (MBMS) is provided. An overview of the DVB-H standard is presented for the sake of discussing
delivery of Mobile TV services to the handheld terminal. A short comparison of competing
delivery mechanisms is also presented (i.e., MediaFLO). As the networks and user equipment (UE)
continue to evolve toward a packet-based system, it is imperative to address certain system related
issues that arise from those techniques.
