“…In deriving (8), it is assumed that the carrier tracking loop bandwidth is much smaller than the input signal bandwidth, so that tracking errors due to Doppler-shifted interferers can be neglected. Instructive results can be obtained by considering the receiver perfectly locked to the desired signal, but the validation of the analytical results should be the subject of future investigation, e.g., by simulation of a multiuser mobile environment along the lines in [20].…”

“…The joint interference sample has the variance jjt while the noise has the variance 2No/Tb. This means that the BER for coherent detection of BFSK is again found from (8), but with NO replaced by 2N0, i.e., with A = 1 and B = 2. In a QPSK transmitter, the source bit stream is split into two slower streams, each with bit rate 1/2rb, and transmitted as two BPSK signals in phase quadrature.…”

“…The local-mean block error probability assuming fast multipath fading can be found by substituting directly the local-mean BER (given by (14) with a , = 0) instead of (8) in (20). Where assuming slow multipath fading, the block error probability has to be averaged over the Rician pdf (3).…”

Abstract-An analytical model is developed for the performance of a microcellular radio network in the presence of co-channel interference and additive white Gaussian noise. The modulation schemes considered are BPSK, BFSK, and QPSK. The multiple-access channel is statistically modeled by one Riciandistributed desired signal and several uncorrelated Rayleigh plus log-normally shadowed interfering signals, propagating according to dual path loss law with a turning point. The performance is determined in terms of bit error rate (BER), outage probability, block error probability, crosstalk probability, and spectrum efficiency, considering both fast and slow multipath fading. The effect of error correction codes, consisting of blocks with equal number of bits, on the performance parameters is also studied.The computational results show that the propagation loss exponents, Rician factor, turning point, and cell size all play a major role in the design of an efficient microcellular system. A proper compromise has to be achieved between spectrum efficiency and bit error rate. The error correction capability of BCH code has a significant effect on the performance for fast multipath fading. However, with slow multipath fading and/or severe shadowing, the effect of error correction is much smaller. Unshadowed fast multipath fading is less harmful than (shadowed or unshadowed) slow multipath fading when appropriate coding is used.

“…Suburban propagation measurements were more random in nature, possibly due to the presence of more than one reflected ray [3], [4]. Studies related to urban propagation mechanisms have received much attention since the vast majority of communications takes place in the metropolis [5]- [7]. Recently, propagation research has begun to concentrate on the characterization of radio channels in indoor environments such as in houses, office buildings, and factories [8]- [10].…”

The uniform theory of diffraction (UTD) developed in Part 1 is used to predict narrow-and wide-band propagation characteristics in tunnels at 900-and 1800-MHz frequencies. Narrow-band propagation characteristics is shown in spatial domain and wide-band propagation in time domain. In empty straight-tunnel environments, propagation exhibits a break-point phenomenon and has very short time delay spread. In empty curved or branched tunnel environments, propagation suffers higher loss. Vehicles cause additional propagation loss and larger varying time delay spread in tunnels. The measured results have validated the accuracy of the theoretical model and provided important information on narrow-band and wide-band propagation characteristics in empty, branched and obstructed tunnels.
