Coded modulation refers to the process of combined and jointly optimized channel coding and modulation scheme. In this paper, block coded modulation using integer codes and its performance isâ€¦ (More)

Let Sk be the gene ra to r ma t r ix o f a [2 k 1 ,k,2 k l ] s implex code; thus all the 2 k 1 co lumns o f S k are dis t inct non-zero b ina ry ktuples . Since g(k, 2 k1) = 2 k _ 1, the b o u n dâ€¦ (More)

First, we compute the number of non-minimal codewords of weight 2dmin in the binary Reed-Muller code RM(r, m). Second, we prove that all codewords of weight greater than 2m âˆ’ 2mâˆ’r+1 in binary RM(r,â€¦ (More)

In this paper we give necessary and sufficient conditions for a Jacket decomposability. Some properties of Jacket matrices are also proved. Jacket matrices are interesting for an eigenvalueâ€¦ (More)

Integer codes are very flexible and can be applied in different modulation schemes. A soft decoding algorithm for integer codes will be introduced. Comparison of symbol error probability (SEP) versusâ€¦ (More)

The problem of integer factorization is of high practical importance because of the widespread use of public key cryptosystems for encryption and authentication of Internet connections. In this paperâ€¦ (More)

We compute the exact value of error probability per symbol (SER) for triangular quadrature amplitude modulation (TQAM) scheme in the case of AWGN channel. Also, we derive an upper and a lower boundsâ€¦ (More)
