    Bandwidth

    etpineda, With regard to symbols vs. bits, the math is simple. 1/2 coding equals two symbols per information bit. 3/4 coding equals four symbols per 3 information bits and so on. There isn't any fixed formula for calculating bandwidth. You have to know several things about your carrier...

    Carrier frequency selection and Bandwidth

    Yeah, you're right. My response was really a theoretical one without too much "real-world" application. But I couldn't tell if the question was one of theory or application so I just threw it out there. Thanks for the follow up. Scott

    Carrier frequency selection and Bandwidth

    Depends on your application I think. For example, in satcom applications, free space loss is directly proportional to frequency. So if your system is power limitted, the higher your carrier freq, the less power you have for higher bandwidth. I admit that this is a fairly uncommon situation...

    Bandwidth

    Bandwidth of a satellite carrier, much like any other, is determined by the information rate, coding implementation, and modulation scheme. 1/2 rate coding produces two symbols for every information bit, 3/4 rate produces four symbols per every three information bits, etc. As for modulation...
