A specific M-ary (d,k) code provides high density recording to a multi-level storage medium. The M-ary (d,k) encoder is implemented using a M-state encoder and a modulo M waveform encoder. 权利要求

In a M-ary signaling system like MFSK, an "alphabet" of M tones is established and the transmitter selects one tone at a time from the alphabet for transmission. M is usually a power of 2, so each tone transmission from the alphabet represents log2 M data bits. MFSK is classed as an M-ary orthogonal signaling scheme because each of the M tone detection filters at the receiver responds only to its tone and not at all to the others; this independence pro… WebTo reflect advantages of a constant phase modulation waveform, the invention provides a pulse amplitude modulated PAM waveform that is a superposition of Qo≤2L-1 PAM component pulses in each symbol interval such that a significant portion of signal energy over each symbol interval is within the Q0 PAM component pulses.
