Tcm-qpsk Provides 2db Gain over Bpsk in Festoon Links
نویسندگان
چکیده
Festoon links are single span subsea links that require no electrically powered amplifiers. Providing longer reach on these types of links enables cost effective, high bandwidth connectivity to more remote locations. TCM-QPSK is an innovative modulation format that works with the hard FEC generation of line cards to provide 2.0dB of extended reach on festoon links compared to differentially coded BPSK.

A Modified Grouped Linear ZF Algorithm Using Different Modulation Schemes for MIMO Systems
A new algorithm for a group iterative linear Zero-Forcing (ZF) receiver for multiple-input multiple-output (MIMO) systems is proposed in this paper. The proposed algorithm merges between the group linear ZF receiver and V-Blast algorithms, where the signals in every group are detected by linear ZF method and then successive interference cancellation detection is applied between the different gr...

Direct-sequence code-division multiple access (DS-CDMA) is currently the subject of much research as it is a promising multiple access capability for third and fourth generations mobile communication systems. The synchronous DS-CDMA system is well known for eliminating the effects of multiple access interference (MAI) which limits the capacity and degrades the BER performance of the system. In ...

This paper will present the design, construction, and implementation of Algebraic-Geometric Irregular Block Turbo Codes (AG-IBTCs). Furthermore, we will evaluate its performance over fast fading channels using different modulation schemes (BPSK, QPSK, 16QAM, and 64QAM). The idea behind the design of AG-IBTC is to overcome the high system complexity of Algebraic-Geometric Block Turbo Codes (AG-B...
