Method for encoding real number m-ary signal and encoding apparatus using same

An M-ary encoding method, the method comprising:

• generating:
• (1) from a first coded sequence, a first number of M1-ary signals;
• and (2) from a second coded sequence, a second number of M2-ary signals;
• and
• multiplexing the first number of M1-ary signals and the second number of M2-ary signals to generate a multiplexed M-ary signal, where M1 and M2 are integers.

A real number M-ary encoding apparatus comprising:

• a coding unit for coding every K binary bit units of binary data (DATA) to generate
• a first input code and a second input code, wherein K is an integer;
• a first signal generator for receiving the first input code and generating N1 number of M1-ary signals;
• a second signal generator for receiving the second input code and generating N2 number of M2-ary signals;
• and
• a first time division multiplexing module for temporally multiplexing the N1 number of M1-ary signals and the N2 number of M2-ary signals to generate a real number M-ary signal, wherein N1, N2, M1, and M2 are integers, respectively,
• and N is an integer equal to N1+N2.

A real number M-ary encoding method comprising:
