Variable-rate network coding for multi-source cooperation [PDF]
, 2011 Multi-Source Cooperation (MSC) techniques, including conventional Code Division Multiplexing (CDM) and Classic Network Coding (CNC) are investigated. We adopt a soft sum-product decoding algorithm for the CNC technique and propose a flexible Variable ...

Enhanced spatial modulation with generalized antenna selection in MISO channels
IET Communications, 2021 Here, an enhanced spatial modulation with generalized antenna selection (ESM‐GAS) for multiple‐input single‐output systems is proposed. Unlike the conventional SM systems, in ESM‐GAS, the number of active antennas is not fixed, but varies from only one ...

Improving the performance of BICM-ID and MLC systems with different FEC codes [PDF]
Advances in Radio Science, 2013 In bandwidth limited communication systems, the high data rate transmission with performance close to capacity limits is achieved by applying multilevel modulation schemes in association with powerful forward error correction (FEC) coding, i.e.

Method of blind reconstruction for trellis‐coded modulation codes
IET Communications, 2014 Since trellis‐coded modulation (TCM) was introduced, it was quickly adopted in modem standards. Unlike blind reconstruction for normal channel coding, blind reconstruction for TCM codes not only requires identifying the correct generator matrix, but also the correct type of constellation mapping. So far this has seldom been reported.

Error probability and capacity analysis of generalised pre-coding aided spatial modulation [PDF]
, 2015 The recently proposed multiple input multiple output (MIMO) transmission scheme termed as generalized pre-coding aided spatial modulation (GPSM) is analyzed, where the key idea is that a particular subset of receive antennas is activated and the specific
