Towards Fully Optimized BICM Transceivers

Towards Fully Optimized BICM Transmissions

Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). A typical BICM configuration is based on a convolutional code, a single bit-level interleaver (S-interleavers), and an equally spaced...

Towards High Data-Rate and Bandwidth-Efficient Integrated Wireless Transceivers

Towards High Speed and Bandwidth Efficient CMOS Wireless Transceivers

We describe an approach to constructing an all-CMOS wireless transceiver capable of transmission speeds of up to 30 Mb/s in the 2.4 GHz ISM band. To achieve robust high bandwidth efficiency communications, the design includes such features as a four element antenna array, adaptive equalization, multi-level QAM transmission, variable baud rates, frequency hopping, and adjustable transmission pow...

Towards Scaling Fully Personalized PageRank

Personalized PageRank expresses backlink-based page quality around user-selected pages in a similar way as PageRank expresses quality over the entire Web. Existing personalized PageRank algorithms can however serve on-line queries only for a restricted choice of page selection. In this paper we achieve full personalization by a novel algorithm that computes a compact database of simulated rando...
