Performance of ieee 802.11a wireless lan standard over frequency-selective, slowly fading nakagami channels in a pulsed jamming environment...802.11a working group approved a standard for a 5 GHz band WLAN that supports a variable bit rate from 6 to 54 Mbps, and orthogonal frequency-division multiplexing (OFDM) was chosen because of its well-known ability to avoid multipath effects while achieving high data rates by combining a high order sub-carrier modulation with a high rate convolutional code....
Asic implementation of a low power baseband-processor for uhf rfid tag... In order to enhance the signal-noise ratio in the return link, spread spectrum technique is used in addition to the FM0 encoding/Miller sub-carrier modulation....
Proposal of a hybrid qam-mppm technique for optical communications systems... Our results reveal that, under the conditions of fixed data rates, bandwidth, and energy per bit, the proposed technique outperforms both traditional QAM and MPPM sub-carrier modulation techniques
Homodyne coherent detection of ask and psk signals performed by a subcarrier optical phase-locked loop... The proposed architecture is based on a new optical phase locked loop founded on sub-carrier modulation and leads to new compact integrated receivers and new transmission formats, thus opening new opportunities for future optical systems
