Coding vs modulation
WebModulation refers to the act of adding the message signal to some form of carrier. The carrier, by definition, is a higher frequency signal whose phase, frequency, amplitude, or … WebModified frequency modulation (MFM) is a run-length limited (RLL) line code used to encode data on most floppy disks and some hard disk drives.It was first introduced on hard disks in 1970 with the IBM 3330 and then in floppy disk drives beginning with the IBM 53FD in 1976.. MFM is a modification to the original frequency modulation encoding (FM) …

These codes support - without further segmentation - up to k=8448 information bits per codeword [3] for a wide range of coderates. Polar codes [1] including CRC concatenation and rate-matching for 5G ...
WebQPSK is a modulation scheme that allows one symbol to transfer two bits of data. There are four possible two-bit numbers (00, 01, 10, 11), and consequently we need four phase offsets. Again, we want maximum separation between the phase options, which in this case is 90°. The advantage is higher data rate: if we maintain the same symbol period ... WebAck/Nack Repetition. A-GPS.
