Scalable traceback technique for channel decoder

A system, comprising:

• an antenna;
• and
• a device connected to said antenna, said device to include:
• a first input to receive a first portion of a state in a state register;
• a second input to receive a second portion of said state in said state register;
• and
• a control unit to load said first portion of said current state to said first input, to load said second portion of said state to said second input, and to generate an output state corresponding to a vector stored in a memory address selected by said first portion of said state and a portion of said vector selected by said second portion of said state.

A method, comprising:

• loading a sequentially stored traceback vector comprising a plurality of bits from a traceback memory array stored in a traceback memory for a first state;
• identifying a traceback bit among said plurality of bits of said loaded traceback vector;
• and
• creating a second state.

An article, comprising:

• a storage medium;
• said storage medium including stored instructions that, when executed by a processor, are operable to:
• load a sequentially stored traceback vector comprising a plurality of bits from a traceback memory array stored in a traceback memory for a first state;
• identify a traceback bit among said plurality of bits of said loaded traceback vector;
• and
• create a second state.
