Abstract:
1. An apparatus, comprising: a memory to store the CSI (Cyclic Shifted Identity) parameter set including at least one dual valued-entry and at least one single-valued entry; an input to receive an LDPC (Low Density Parity Check) coded signal; and an LDPC decoder to decode the LDPC coded signal using an LDPC matrix, including a plurality of sub-matrices each having the common size, such that at least one of the plurality of sub-matrices corresponding to the at least one dual valued-entry of a CSI parameter set and at least one additional of the plurality of sub-matrices corresponding to the at least one single-valued entry of the CSI parameter set; and wherein: the at least one of the plurality of sub-matrices corresponding to the at least one dual valued-entry generated from a first preliminary CSI sub-matrix corresponding to a first portion of the at least one dual valued-entry and from a second preliminary CSI sub-matrix corresponding to a second portion of the at least one dual valued-entry.
