What types of spread spectrum technology does the FCC specify in the Codes of Federal Regulation?

The Federal Communications Commission (FCC) specifies two primary types of spread spectrum technology in the Code of Federal Regulations: Direct Sequencing Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

Direct Sequencing Spread Spectrum involves spreading the data signal over a larger bandwidth than the minimum required, using a pseudorandom noise code to modulate the signal. This technique helps improve resistance to interference and can provide better security against eavesdropping.

Frequency Hopping Spread Spectrum, on the other hand, rapidly switches the carrier frequency among many different frequencies, which makes it more difficult for unauthorized listeners to intercept the signal. This technique contributes to improved reliability and security by reducing the likelihood of interference from jamming or other systems operating on a single frequency.

These two technologies are outlined in the regulations due to their significance and efficiency in various communication applications, making them central to the usage and development of wireless communication systems.

The other options do not specifically align with the FCC's regulations concerning spread spectrum technology. Homogeneous and heterogeneous systems do not describe spread spectrum techniques but rather refer to the composition of a system in terms of uniformity and diversity. Microwave and infrared systems are types of communication mediums but do not pertain directly to spread spectrum methodologies and
