  1. 11. Investigation of LDPC code in DVB-S2

    University essay from Datorteknik; Tekniska högskolan

    Author : Hanxiao Ge; [2012]
    Keywords : LDPC code; DVB-S2; Restructured parity-check matrix; Layered message passing LMP ; Reconstructed decoding table;

    Abstract : As one of the most powerful error-correcting codes, Low-density parity check codes are widely used in digital communications. Because of the performance of LDPC codes are capable to close the shannon limited extraordinarily, LDPC codes are to be used in the new Digital Video Broadcast-Satellite-Second Generation(DVB-S2) and it is the first time that LDPC codes are included in the broadcast standard in 2003.

  3. 12. DEVELOPMENT OF ACOUSTIC MODELS FOR HIGH FREQUENCY RESONATORS FOR TURBOCHARGED IC-ENGINES

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Zheng Wang; [2012]
    Keywords : Noise; turbo compressor; silencer; resonator;

    Abstract : Automotive turbo compressors generate high frequency noise in the air intake system. This sound generation is of importance for the perceived sound quality of luxury cars and may need to be controlled by the use of silencers. The silencers usually contain resonators with slits, perforates and cavities. READ MORE

  4. 13. Turbo Equalization for HSPA

    University essay from Kommunikationssystem

    Author : Cagatay Konuskan; [2010]
    Keywords : Turbo equalization; MMSE; HSPA; ISI; decoding; equalization; low complexity; HARQ;

    Abstract : New high quality mobile telecommunication services are offered everyday and the demand for higher data rates is continuously increasing. To maximize the uplink throughput in HSPA when transmission is propagated through a dispersive channel causing self-interference, equalizers are used. READ MORE

  5. 14. Hardware Accelerator for Duo-binary CTC decoding : Algorithm Selection, HW/SW Partitioning and FPGA Implementation

    University essay from Institutionen för systemteknik

    Author : Joakim Bjärmark; Marco Strandberg; [2006]
    Keywords : Error Correcting Codes; Turbo Codes; Decoding; Implementation; FPGA;

    Abstract : Wireless communication is always struggling with errors in the transmission. The digital data received from the radio channel is often erroneous due to thermal noise and fading. The error rate can be lowered by using higher transmission power or by using an effective error correcting code. READ MORE
