“…The second term on the right-hand side of (5) equals the definition [ 141 of the characteristic function (or Laplace transform) of the pdf of the instantaneous joint interference power p,, in the point U = z/plo [15]. For incoherent (power) addition of n uncorrelated interference signals, the outage probability can be written on the form of a product 7 of n Laplace images, viz.,…”

Abstract-A novel mathematical method is presented to express the outage probability for a desired radio signal received from a mobile transmitter in the presence of multiple interfering signals with combined lognormal and Rayleigh fading. In contrast to previously reported analysis, this exact method avoids approximation of the pdf of the received powers of the various signals. This is useful in determining the spectrum efficiency and performance of (interference-limited) radio networks for highcapacity cellular telephony, two-way paging, packet radio and other mobile data networks.

“…For channels without shadowing (0 = 0), probability (11) reduces to a simple analytic expression, as, e.g., in [5], [9], [lo], [15]. Schwartz and Yeh's method [6]: in the latter method at least 40 complicated terms of a series have to be considered for each contributing interfering signal [6].…”

“…Several papers deal with the performance analysis of FH systems under PBI and MAI, when non-coherent modulation is employed with Reed-Solomon or convolutional codes (see for example, [3]- [6]). In the context of cellular systems, such as GSM, the advantages of frequency and interference diversity, that ensue from combining slow FH and coding, are analyzed in [7]- [9].…”

Frequency hopping (FH) combined with coding is a popular technique in wireless communication applications. Motivated by the commercial system outlined in [1], this paper investigates the performance of a coherent FH Multiple Access (FH-MA) cellular system, where hopping patterns are constructed from Latin squares. Some of the patterns carry pilot symbols, which the users track to estimate the channel on the data patterns and perform coherent detection. The Latin squares construction enables us to analytically evaluate the bit error probability (BEP) over each data pattern, when convolutional codes are employed for error protection. The focus of our work is to precisely determine the effect that frequency and interference diversity, ensuing from FH, have on the coded performance.Regarding frequency diversity, it is shown that the performance can vary widely for different Latin squares. Moreover, under pilot-assisted channel estimation, a performance tradeoff is observed, as an increasing frequency selectivity results in more diversity, but also more inaccurate channel state information. With respect to interference diversity, we analyze the performance when the interference power variations are perfectly known or ignored by the receiver. Our results confirm that interference tracking is important in harnessing the error correcting power of convolutional coding.

“…In [2] an information theoretic approach for analysis of various multiple access schemes is given considering various propagation factors like path loss, shadowing and fading. However the authors consider various multiple access schemes without considering any particular modulation scheme, large-scale propagation models are considered which do not capture the time dispersive multipath effects in indoor radio channels.…”

The IEEE 802.15 Wireless Personal Area Networks (WPAN) study group has been working on evolving a standard for shortrange wireless connectivity between low complexity and low power devices operating within the personal operating space (POS). The scenarios envisioned for WPANs are likely to involve a large number of POSs operating in an indoor environment. Among short-range wireless technologies, Bluetooth TM t based Mhoe connectivity comes closest to satisfying the WPAN requirements. Bluetooth provides a gross rate of 1 Mbps per network and allows several such networks to overlap using frequency hopping. The 'aggregate throughput' thus achieved is much higher than 1 Mbps. In the absence of external interfering sources, aggregate throughput is limited by self interference which depends upon, (i) physical layer parameters like hopping rate, hopping sequences, transmitted power, receiver sensitivity, modulation, forward error correction (ii) channel characteristics like coherence bandwidth and coherence time (iii) spatial characteristics. In this work we consider the problem of finding the capacity of Bluetooth based ad-hoc systems by accurately modeling the Bluetooth physical layer and the indoor wireless channel. We predict the throughput in Bluetooth based M-hoe systems as a function of a generalized set of parameters using realistic scenarios and assumptions.
