This coherent combining enables, for example, wireless devices located in an extended coverage area of a cell served by the base station to synchronize to the cell using a shorter synchronization signal than that which would be required if only non-coherent combining were used.

Abstract: Particular embodiments provide a method for delivering data in the upstream direction without the need for upstream radio frequency (RF) modulation. For example, in some embodiments, an optical network may reach to a gateway associated with a user device. The gateway may receive digital baseband data from the user device in the upstream direction. The gateway can then send the digital baseband data through the optical network without modulating the digital baseband signal via radio frequency. At the headend, because no modulation is performed in the upstream direction, there is no need for de-modulation in the headend. In one embodiment, a scheduler-based approach is used to avoid instances of optical beat interference in the upstream direction as only one upstream device that may interfere with other devices may be able to send data at one time.

Abstract: Photonic integration has primarily sought to exploit optical parallelism through wavelength division multiplexing whilst in many instances “brute-force” time division multiplexing offers benefits through reduced complexity and cost. However, photoreceivers are primarily the same now for operation at 10 Gb/s, 20 Gb/s, 40 Gb/s and above as 20 or 25 years ago and exploit the same optical detection—amplification—logic processing design. However, high speed low cost electronics ca be leveraged in conjunction with optical time sampling and logic to provide a new design paradigm. An incoming XGbs?1 optical data stream is sampled and processed by N photodetectors each operating at (X/N)Gbs?1 rather than the current direct XGbs?1 front-end of the prior art. Flexibility for the designer in establishing N within optical layer constraints, electronics capabilities etc.
