For the extremely high sampling rate and high resolution required for multi-Gigabit orthogonal frequency division multiplexing (OFDM) communication systems, time-interleaved analog-to-digital converters (ADCs) are being considered. However, in …
In traditional multicarrier systems, the pilot carriers used to estimate the channel are placed as uniform as possible over the bandwidth. However, with the raise of cognitive radio systems, where the multicarrier system is used by the secondary …
We propose an iterative decision-directed joint frequency offset (FO) and channel estimation algorithm in a known symbol padding (KSP) orthogonal frequency division multiplexing (OFDM) system, where the guard interval is filled with pilot symbols. …
The quality of experience (QoE) of IP-packetized streaming video is affected by both packet loss and packet delay variations. When the network delivering the video content contains a wireless link, occasional deep fades give rise to bursts of packet …
In this paper, we propose an iterative 'turbo' channel estimation algorithm for known symbol padding (KSP) OFDM, where the guard interval is filled with pilot symbols. Additional pilot symbols are transmitted on some of the OFDM carriers. The channel …
