Implementation issues of adaptive OFDM in mobile radio environment
(The Institution of Engineers, Malaysia, 2004-09)
A review of adaptive modulation with other related issues as part of link adaptation in an OFDM system is presented. Issues such as
channel estimation, channel coding, Multiple Input and Multiple Output (MIMO) system are ...
Coded space-time-frequency OFDM over IEEE 802.11 fading channels
(The Institution of Engineers, Malaysia, 2007-03)
This paper will present a 4-transmit and 1-receive (4Tx:1Rx) antenna system of coded space-time-frequency in conjunction with
orthogonal frequency division multiplexing (Coded STF-OFDM). STF block code is concatenated ...
Guided scrambling as a peak to average power ratio reduction technique for digital video broadcasting-terrestrial 2
(The Institution of Engineers, Malaysia (IEM), 2017-12)
Analogue Broadcast Transmitters are being replaced by Digital Transmitters based on standards using Orthogonal Frequency Division Multiplex (OFDM). However, high Peak to Average Power Ratio (PAPR) is limiting the performance ...
