- A Pseudorandom Postfix OFDM Modulator - Semi-Blind Channel Estimation and Equalization
- This paper details a new Orthogonal-Frequency-Division-Multiplexing OFDM modulator based on the use of a PseudoRandom Postfix PRP-OFDM and discusses low-complexity equalization and channel estimation/tracking architectures. The main property of this new modulation scheme is the ability to estimate and track the channel variations semi-blindly using order-one statistics of the received...

- Novel Segmented Cascade Electroabsorption Modulator With Improved Bandwidth-Extinction Product
- Standard lumped-element Electroabsorption Modulators EAMs are the workhorse of InP integrated modulation, due to their simple operation and small size. A short length of passive waveguide is appended to a laser or other photonic circuit, and driven with a variable negative voltage. A voltage-dependent Franz-Keldysh absorption, modulates the optical input....

- Current-Mode Modeling for Peak, Valley and Emulated Control Methods
- Current-mode operation: An ideal current-mode converter is only dependent on the dc or average inductor current. The inner current loop turns the inductor into a voltage-controlled current source, effectively removing the inductor from the outer voltage control loop at dc and low frequency. The modulator gain is dependent on the...

- On the Design of an FPGA-Based OFDM Modulator for IEEE 802.16-2004
- Current and future communication schemes tend to use OFDM systems in order to provide high baud rates and less inter symbol interference. Some examples are 802.11, 802.16, MC-CDMA, Digital Video Broadcasting, Wireless USB and Wireless Firewire. Trying to provide a solution to the new emerging devices, slow standard adoption and...

- A New Adjustable Hybrid Spread OFDM Modulator
- The improvement brought by Successive Decoding algorithms is marginal when applied to uniformly spread OFDM-CDMA systems, because of the harmonization of the Signal to Noise Ratio across the subbands at the receiver. Thus this paper proposes a new Hybrid Spread OFDM SOFDM transmission scheme in which the spreading of the...
