Final answer:
To calculate the number of FDMA channels in a 100 MHz spectrum with each channel having a 300 kHz bandwidth and 10 kHz guard band, add the channel bandwidth and guard band,
Step-by-step explanation:
The correct answer is option to find the number of channels available in an FDMA system with a total of 100 MHz spectrum allocated, the channel bandwidth is 300 kHz, and the guard band is 10 kHz between each channel,
you would first add the channel bandwidth and guard band to determine the total bandwidth required for each channel. This is 300 kHz + 10 kHz = 310 kHz per channel.
To find out how many such channels can fit in the 100 MHz spectrum, you divide the total spectrum by the bandwidth per channel:
100 MHz / 0.310 MHz = 322.5806
Since we cannot have a fraction of a channel, the answer is rounded down to the nearest whole number, which means there are 322 channels available in the FDMA system.
The correct answer is option D.
In a frequency division multiple access (FDMA) system, the total spectrum is divided into channels, and each channel is allocated a specific range of frequencies.
Given that the total spectrum allocated is 100 MHz, and the channel bandwidth is 300 kHz, we can calculate the number of channels as follows:
Number of channels = Total spectrum allocated / Channel bandwidth
Number of channels = 100 MHz / 300 kHz
Number of channels = 100,000 kHz / 300 kHz
Number of channels = 333.33 channels (rounded down)
Therefore, the number of channels available in the FDMA system is 333 channels.
