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...

By exploiting the wireless multiple-input multiple-output (MIMO) channel structure, a brand new space-time code design criterion is derived. Based on...

In this letter, we show that Chikazawa-Yamagishi ID-based key sharing scheme and its improved versions do not satisfy the forward secrecy. Also, we pr...
