A low complexity feedforward symbol-timing estimator based on the conditional maximum-likelihood principle is proposed. An approximation is applied to...

In this letter, we present a framework for constructing rate-compatible low-density parity-check (LDPC) codes. The codes are linear-time encodable and...

A simplified branch metric and add-compare-select (ACS) unit is presented for use in trellis-based decoding architectures. The simplification is based...

For high data rate applications, the implementation of iterative turbo-like decoders requires the use of parallel architectures posing some collision-...

In this letter, we propose a hybrid access scheme for satellite communications, taking into account the long propagation delay. The proposed scheme us...
