It is well-know that carrier frequency offset in the subcarriers of orthogonal frequency division multiplexing (OFDM) leads to intercarrier interference (ICI); therefore, system degradation occurs. Nevertheless, this issue may effectively be mitigated via the pulse shaping filter method. In this manuscript, we present the improved double jump linear combination (IDJLC) function. With the goal of minimizing...
A major drawback of orthogonal frequency division multiplexing (OFDM) is the frequency offset sensitivity. It mainly leads to inter-carrier interference, which can effectively be reduced by employing the pulse shaping filter method. In this manuscript, we present and then optimize the improved double-jump 1 (IDJ1) pulse for digital video broadcasting over cable 2 OFDM systems. Our function is finally...
It is well known that the performance of orthogonal frequency division multiplexing is highly sensitive to frequency offset. In this paper, we present theoretical results to assess the intercarrier interference reduction using general pulse shaping filters in digital video broadcasting over cable (DVB-C) systems. These pulses are characterized by only one design parameter, known as the roll-off factor...
Intercarrier interference severely limits orthogonal frequency-division multiplexing (OFDM) performance. Nevertheless, it can be mitigated by using Nyquist-I pulse shaping filters. In OFDM-based systems, we assess the exponential linear (EL) pulse and compare it with the best Nyquist-I pulses. EL pulse is characterized by having one additional design parameter, known as β. It is first optimized through...
