“…A comparison of the developed model with above cited models gives large difference because of different geographical conditions in India. Therefore for accurate path loss prediction, field measurements must be performed and the measured data can be used to correct the existing model or to develop a new model [8]and [10]. The simulated results indicated in Table 1 shows that bit error rate BER increases with the vehicle speed.…”

“…Simulation of fading Models based on lcr and adf [5] To observe the nature of received signal envelop the rural scenario is considered. As discussed in [8] [9] ,and [10] the signal strength received at the mobile receiver is a random process which varies lognormaly with the distance travelled by the mobile receiver away from the transmitter. figure 5 shown below is the Matlab simulation of received signal strength variation as a function of distance.…”

The mobile radio channel places strong limitations on the performance of wireless communication systems because the transmission principle in wireless communication is more complex than those of the wired networks. In this paper we discuss the radio propagation with an objective to provide an overview of various characteristics of radio channel and an understanding of the process and factors that influences these characteristics. Section I describe a typical outdoor scenario for terrestrial mobile radio channel and principle causes of information loss (multipath fading). Section II presents the various radio channel characteristics like path loss which is used to denote the local average received signal power relative to the transmit power and helps in providing the information on coverage area. Other higher order statistical characteristics such as level crossing rate (lcr) and average duration of fade (adf), which relates the time rate of change of the received signal to the signal level and velocity of the mobile, are also considered to study the influence of short term fading on the performance of the wireless system. Section III contains the observed path loss and its comparison with the simulated path loss propagation models. Lcr and adf are obtained from the received signal envelop in section IV to study the system performance. The simulated results obtained in section III and section IV provide valuable information on coverage area, and choice of suitable data rate, word length, modulation, and coding schemes as stated in table1.

In this paper we have emphasized on the short term fading of the mobile communication channel and made an attempt to investigate its influence on the performance of mobile communication system. Level crossing rate and average duration of fade are considered to characterize the fast fading nature of channel. Other factors like carrier frequency, speed of the mobile have been investigated and found that BER performance of the system is greatly influenced by multipath fading.

“…Rafiq and Patzold [24] have investigated the influence of shadowing level on the capacity statistics of channels modeled by Suzuki process. Considering, the wide applicability of log-normal fading in wireless system, it would be useful to investigate the impact of shadowing level (V dB ) on capacity statistics.…”

The analytical expression for the MGF (Moment Generating Function) of the channel capacity in log-normal fading environment is derived. Using MGF, the closed form expression for higher order moments of channel capacity are computed as a rapidly convergent infinite series. Explicit expression for error and its upper bound resulting on account of truncation of series are obtained. Numerical results based on truncated infinite series are found to be in excellent agreement with those based on Monte Carlo simulation and Gauss Hermite method. Statistical measures like coefficient of variation, skewness and kurtosis are obtained for different values of shadowing level over a range of practical interest. It is found on the basis of skewness and kurtosis that gaussian approximation for channel capacity in log-normal fading environment is not in general valid over the entire range of dBspread.
