Welcome to my site!
Multi Carrier PSK
is using the same protocol for PSK-R but adding the information to different carriers

The PSKR modes use binary convolution to generate two bits per varicode bit at the same symbol rate.  These modes us Rate R=1/2, Constraint length K=7 with diagonal interleavers, variable in size to keep the timing between redundant information constant. 
The number of interleavers for each baud rate is 40, 80 and 160 for PSK125R, PSK250R and PSK500R respectively.  PSKR modes use the MFSK varicode which provides a small increase in average speed of about 13%.

The PSK63FEC (also PSK63F in short) is identical to the PSKR modes but for the absence of an interleaver.
