Joint Demapping and Decoding for DQPSK Optical Coherent Receivers
نویسندگان
چکیده
We present a low-complexity joint demapper-decoder scheme for coherent optical receivers with DQPSK modulation. The new technique reduces to 0.7dB the gap between QPSK and DQPSK in 100Gb/s coherent optical systems.

On Iterative Receivers for Non-Coherent Channels
It is well-known that optimal receivers for many wireless communication systems employ joint channel estimation and decoding. Since this is almost always too computationally complex, we consider iterative receivers that approximate joint estimation and decoding by iterative algorithms. Continuous-valued variables such as the channel phase response are often difficult to handle in these algorith...
متن کاملJoint Iterative Equalization, Demapping, and Decoding with a Soft Interference Canceler
High-level modulation alphabets offer an additional degree of freedom compared to the binary case, since several mappings from bits to symbols are possible. Recently, it was shown that using different mappings rather than Gray coding, a tremendous performance gain for AWGN channels can be obtained with iterative demapping and decoding. In this paper we include iterative demapping in a turbo equ...
متن کاملOn downlink channel adaptation for TDD based LMDS systems
This paper considers several aspects concerning the downlink channel adaptation for TDD (Time Division Duplexing) based LMDS (Local Multipoint Distribution System) systems. First the requirements with respect to round-trip-time and complexity are considered, then a candidate scheme for the Forward Error Correction (FEC) scheme is described. The results of a simulation study of the performance o...
متن کاملAnalysis of signed chromatic dispersion monitoring by waveform asymmetry for differentially-coherent phase-modulated systems.
We analytically study received waveform asymmetries induced by chromatic dispersion (CD) for signed CD monitoring in differential quadrature phase-shift keying (DQPSK) systems and show that the asymmetries are results of differential detection and the ±π/4 phase shifters used in conventional DQPSK receivers. The theoretical insights developed help explain various published results on signed CD ...

Mday, M arch 24 transmission system was 20 Gb/s, while the symbol rate was 10 Gbaud (=10 GS/s). The second MZ modulator was used as a pulse carver to generate RZ-DQPSK signals. For the 20-Gb/s DQPSK receivers, two 100-ps DIs with two separate balanced receivers are generally required to simultaneously demodulate the two 10-Gb/s data streams contained in the 10-Gbaud DQPSK signal [4]. However, w...
