This letter presents a graph-theoretic method for constructing low-density parity-check (LDPC) codes from connected graphs without the requirement of...
We optimize irregular low-density parity-check (LDPC) codes to closely approach the independent and uniformly distributed (i.u.d.) capacities of parti...
In this letter, we present formulas for the pairwise error-event probability (PEP) and bit error probability (BEP) of trellis-coded unitary space-time...
In this letter, a multi-phased CDMA system employing a variable spreading gain (VSG) approach is proposed for high-rate applications, based on four al...
We consider cyclic prefixed single carrier and adaptive multicarrier transmission over a frequency selective channel. We compare the achievable bit ra...
