Which technique is used for allocating capacity on a satellite channel using fixed assignment FDM?

Which technique is used for allocating capacity on a satellite channel using fixed assignment FDM? Correct Answer FDMA

Multiple access system in a satellite earth station has the following advantage:

  • Maximize system capacity and efficiency.
  • Resource allocation and spectrum reuse can be possible dynamically.
  • The bandwidth allocation within the channel can be done by FDMA, TDMA, and CDMA.
    FDMA: Frequency division multiple access
    TDMA: Time-division multiple access
    CDMA: Code division multiple access

 

The features of FDMA are as follows:

  • FDMA allots a different sub-band of frequency to each different user to access the network.
  • If FDMA is not in use, the channel is left idle instead of allotting to the other users.
  • Tight filtering is done here to reduce adjacent channel interference.
  • The base station BS and mobile station MS, transmit and receive simultaneously and continuously in FDMA.

The capacity of a band-limited additive white Gaussian noise (AWGN) channel is given by $$C = W\,{\log _2}\left( {1 + \frac{P}{{{\sigma ^2}W}}} \right)$$     bits per second (bps), where W is the channel bandwidth, P is the average power received and σ2 is the one-sided power spectral density of the AWGN. For a fixed $$\frac{P}{{{\sigma ^2}}} = 1000,$$   the channel capacity (in kbps) with infinite bandwidth (W → ∞) is approximately
