Low complexity FEC Systems for Satellite Communication
In order to address low power, low processing delay requirement of emerging satellite communication systems, there is a need for low complexity small block length forward error correction (FEC) codes. Furthermore the new trends towards the convergence of wireless and satellite terminals would also mean co-existence of support for very short and the long blocks of data in the same device. In thi...
متن کاملNew Generation FEC in Satellite Systems
Due to the inherent ‘long-haul’ nature of satellite communication and the transition of the payload information through many phases of modulation, frequency conversion, amplification, transmission and demodulation, it is not surprising that the occurrence of errors can be high. Fundamental transmission times of around 500ms point towards the use of Forward Error Correction (FEC) techniques (in ...
متن کاملLow Complexity Channel Estimation for OFDM based Satellite Systems
The demand for high data rate and high user mobility has driven modern wireless communications into a new era, in which advanced technologies are developed to facilitate the fulfilment of such demands, as well as to guarantee the quality of service of transmissions under adverse channel conditions. OFDM has become a popular choice for wideband high data rate communication systems due to its str...
متن کاملA Low-Complexity Turbo Equalizer for OFDM Communication Systems
With the growing demand for mobile communications, multicarrier (MC) schemes are receiving an increasing amount of attention, primarily because they handle frequency selective channels better than ordinary single-carrier schemes. However, despite offering several advantages, MC systems have certain weak points. One is their high sensitivity to interchannel interference (ICI). The influence of D...
متن کاملA Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems
In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
