1. Synchronization and data detection in long-code CDMA systems / Pei Xiao %C Göteborg
Sammanfattning : .... LÄS MER
2. Low-density parity-check codes : unequal error protection and reduction of clipping effects
Sammanfattning : The invention of low-density parity-check (LDPC) codes made reliable communication possible at transmission rates very close to the theoretical limit predicted by Shannon. However, communication close to the Shannon limit requires very long codes and results in long delay and high encoder and decoder complexity. LÄS MER
3. Channel Coding and Multiuser Detection for CDMA and Wireless Communications
Sammanfattning : Next generation wireless communication systems will require support for many different applications as well as improved quality compared to existing second generation systems like GSM (Global System for Mobile communications). Since there will be more users and higher data rates, the capacity must also be increased. LÄS MER
