[amp_mcq option1=”Power efficiency” option2=”Spectral efficiency” option3=”Transmission efficiency” option4=”Modulation eficiency” correct=”option2″]<\/p>\n

The correct answer is B. Spectral efficiency.<\/p>\n

Spectral efficiency is a measure of how much information can be transmitted over a given bandwidth. It is typically measured in bits per second per hertz (bps\/Hz). A higher spectral efficiency means that more information can be transmitted over the same bandwidth, which can lead to improved data rates.<\/p>\n

There are a number of ways to improve spectral efficiency, including using modulation techniques that allow for more bits to be transmitted per symbol, using multiple antennas, and using error correction coding.<\/p>\n

In the context of the question, increasing the bits per symbol ultimately improves spectral efficiency. This is because more information can be transmitted per symbol, which means that less bandwidth is required to transmit the same amount of information.<\/p>\n

The other options are incorrect. Power efficiency is a measure of how much power is required to transmit a given amount of information. Transmission efficiency is a measure of how much of the transmitted information is received correctly. Modulation efficiency is a measure of how well a modulation scheme can be used to transmit information.<\/p>\n

I hope this explanation is helpful. Please let me know if you have any other questions.<\/p>\n","protected":false},"excerpt":{"rendered":"
