“…When the interfering system signal overlaps with the victim system, an attenuation loss due to propagation and overlapping occurs, this loss called minimum attenuation loss (L min ), in dB, and can be evaluated by the following formula [6]:…”

“…In this method, the power loss of interfering signal,L i , for the OFDM-based LTE-Advanced system as an interferer can be derived from a power spectral density analysis of the OFDM signals which overlap with that of FM broadcasting. By assuming that a rectangular pulse of OFDM system employs N subcarriers, the OFDM signal PSD, S ofdm ( f ), is expressed as follows [6].…”

“…Therefore, the power loss of interfering signal can be represented by bandwidth overlapping ratio. This ratio can be computed by applying the integration on the composite received PSD over the bandwidth of receiver and the result is divided by the overall power in the original transmitter PSD [6,9]. Consequently, as of Fig.…”

“…Moreover, this method can be only adopted as a special case of the "static" interference situations. Coexistence and sharing of IMT-Advanced with point-to-point fixed services (FS) have been carried out by using the Advanced-MCL (A-MCL) method, which was derived to overcome the restriction of MCL method [6,7]. A-MCL method calculates the interference power depending on overlapping of the power spectral density (PSD) of the OFDM signals with the other systems that have a rectangular PSD shape such as FS system.…”

The surest way to guarantee that multiple wireless systems can concurrently exist harmlessly, when operating in the same or adjacent channel, is by analyzing spectrum overlapping. This paper proposes a more accurate model to evaluate the interference power from co-channel and adjacent channel of orthogonal frequency division multiplexing-based long term evolution-advanced (LTE-Advanced) towards broadcasting frequency modulation systems at 800 MHz. Power spectral density overlapping factor is employed, and closed form of the interference power loss is derived. Numerical results demonstrate that the proposed method evaluates more exact interference power than the advanced minimum coupling loss (A-MCL) method, where the co-channel and adjacent channel interference powers are reduced by 1.3 and 3 dB, correspondingly, compared to that obtained using the A-MCL method. This decreases the minimum separation distance between the two systems, which can eventually lead to efficient radio spectrum resources utilization.

“…Three basic schemes dedicated to analysis of the interference potential between systems that have been addressed in previous work [1] [2], namely, the minimum coupling loss (MCL) method, the advanced minimum coupling loss (A-MCL) and the Monte Carlo method. First, the MCL method utilizing diagnostic estimation is simple to use and can be constructed in less time than the other models.…”
