Memory-based Crosstalk Avoidance Codes

Abstract

Codewords generated inmemory-based crosstalk avoidance encoding satisfy a specified crosstalk upper-bound requirement with respect to the previous codeword on the bus. The codeword is generated based not only on the current data word, but also on the previously transmitted codeword. Such a code is therefore called „memorybased code“. The decoder also uses the current received codeword and either the previous received codeword or the previous decoded data word to decode the current data word. The memory depth of CACs we consider is one.
