Intralevel Interleaving for BICM in OFDM Scenarios
نویسنده
چکیده
Interleaver design for bit-interleaved coded modulation in highly bandwidth-efficient transmission is investigated. Based on an equivalent channel model with parallel binary input channels, the variation of the so-called bit level capacities is identified as an additional source of “fading” that has to be taken into account for interleaver design. We assess the more appropriate approach of intralevel interleaving and present numerical results that support the superiority of the suggested design over global interleavers.

Adaptive Modulation and Interleaving for BICM-OFDM
The optimisation of communication systems with respect to the applied channel code is a more recent topic in the field of adaptive communications compared to the optimisation of uncoded transmissions. Besides the information theoretical statements the applied codes are not perfect but practical codes which poses the additional problem to capture the structure and overall behaviour of a code suf...

Space-Time Block Coded (STBC) In-phase Quadrature-phase (IQ)-interleaved Coded Modulation (CM) schemes are proposed for Orthogonal Frequency Division Multiplexing (OFDM). Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iteratively Decoded BICM (BICM-ID) schemes having a similar decoding complexity are employed in conjunction with 16-level Quadrature...

Two coded modulation schemes with the same bit-rate and decoding complexity are designed and compared. The first scheme combines Trellis Coded Modulation (TCM), symbol interleaving, and orthogonal frequency-division multiplexing (OFDM). The second system combines bit-interleaved coded modulation (BICM), based on a convolutional code, with OFDM. Both systems are combined with a space-time block ...

Bit-interleaved coded modulation (BICM) is a robust multiplexing technique for achieving multiplexing gain in multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems. However, in order to benefit maximally from the various advantages offered by BICM-based MIMO-OFDM systems, availability of accurate MIMO channel state information (CSI) at the receiver end ...

Bit-interleaved coded modulation (BICM), together with orthogonal frequency-division multiplexing (OFDM) signaling, has found its application in many recent wireless standards. BICM-OFDM systems are able to simplify the design of coding and modulation with various information rates for link adaptation. Furthermore, they provide robustness against frequencyselective fading channels. The combinat...
