例句與造句

1. The frequency reuse factor is the rate at which the same frequency can be used in the network.
2. Spread spectrum makes it possible to have as low a frequency reuse factor as 1, if each base station is divided into 3 cells by means of 3 directional sector antennas.
3. The frequency reuse factor in most countries is approximately 15, meaning that only one out of 15 transmitter sites can use the same channel frequency without problems with co-channel interference, i . e . cross-talk.
4. Common values for the frequency reuse factor are 1 / 3, 1 / 4, 1 / 7, 1 / 9 and 1 / 12 ( or 3, 4, 7, 9 and 12 depending on notation ).
5. The frequency reuse factor for local programmes and multi-frequency broadcasting networks ( MFN ) is typically 4 or 5, resulting in 1 / 4 / ( 0.26 MHz ) = 0.96 programmes / transmitter / MHz.
6. It's difficult to find frequency reuse factor in a sentence. 用frequency reuse factor造句挺難的
7. In a cellular system based on frequency-division multiple access ( FDMA ) with a fixed channel allocation ( FCA ) cellplan using a frequency reuse factor of 1 / 4, each base station has access to 1 / 4 of the total available frequency spectrum.
8. Code division multiple access-based systems use a wider frequency band to achieve the same rate of transmission as FDMA, but this is compensated for by the ability to use a frequency reuse factor of 1, for example using a reuse pattern of 1 / 1.
