802.11n Modem IP

802.11n Modem IP OFDM Modems are used in systems which are subjected to large frequency selective fading which results in inter symbol interference (ISI). By using a cyclic prefix (CP), OFDM system provides robustness against ISI. Further there is no need of complex adaptive equalizer as in single tone system. Hence, OFDM modem have found their place in most of…

Turbo Product Code [TPC]

Turbo Product Code [TPC] The BCH based TPC decoder is used for Forward Error Correction (FEC) in systems where transmitted data is subjected to errors before reception, e.g., communications systems. Fully synchronous design using a single clock Code block length variable from 31*31 to 127*127 symbols Block length can be changed at compile time Block length can be changed at…

AFDX

Avionics full-duplex switched Ethernet (AFDX) technology enables deterministic Ethernet networking for avionics and aircraft systems. The 100 Mbit/s AFDX LFT End System card supports rate-constrained traffic shaping to ensure bounded latency and jitter for deterministic Ethernet networking, as described in ARINC 664 standards. The card can be used for production system integration and provides high-integrity redundancy management as well as…

TCC FEC Codec

The TCC is used for Forward Error Correction (FEC) in systems where transmitted data is subjected to errors before reception, e.g., communications systems, disk drives, and so on. TCC Codes are part of recently invented ‘Iterative decoders’, which involves multiple iterations to improve the performance. Iterative decoder shows improved performance compared to legacy convolution codes. TCC codes outperform Convolution codes…

Digital Signaling and Their Inter-conversion

Nowadays we face many ICs which have different interfaces like LVPECL, LVDS, CML, LVCMOS, TTL, HSTL etc. While designing a PCB schematic, interfacing of one IC with another IC with different signalling supported, becomes a hurdle to desgin the circuit. In this case a desginer always look for an ASIC which can act as a bridge between two signalling…… Download
