Abstract

The invention consists of a distribution of softdeci- sion bits for dibit processing. At present it is solved through the use of several demodulators and bit serial processing units. The decoding of softdecision bits is usually achieved by converting the parallel softdecision inputs to serial and decoding the serial bits. The term dibit is syno- nym für two parallel bits to double the process speed.
