title: Novel design of N-dimensional CAP filters for 10  Gb/s CAP-PON system.
abstract: We propose a novel method to design N-dimensional carrierless amplitude and phase modulation (CAP) filters. Theoretical analysis and experimental results show that by using the proposed method, the required iteration steps for filters design are significantly decreased, and the orthogonality between CAP filters could be maintained even with lower cutoff frequency compared with the existing methods. Furthermore, we successfully demonstrate a 10 Gb/s 4-dimensional CAP data transmission experiment over 25 km standard single mode fiber. The results show that the proposed N-dimensional CAP filter design method has potential applications in low-cost and high speed CAP-PON systems.
