Abstract: An integrated receiver with multiple, independently synchronized clock signals for multiple channel transport stream decoding and delivery substantially implemented on a single CMOS integrated circuit is described. An integrated circuit that services two satellite programs must generate and distribute corresponding time domain clocks to the various components of the integrated circuit. The transport block that receives one or more satellite signals from a demodulating block will extract program clock recover values from each signal being decoded and use these values to produce an error signal or control word that serves as an input to a clock generator. Based upon this input, the clock circuit will produce a corresponding time domain clock for each channel serviced by the integrated circuit. The output of the clock circuit is distributed to the various processing blocks within the integrated circuit that operate upon channel content received and processed by the transport block.

Abstract: Cancellation of interference in a communication system with application to S-CDMA. A relatively straight-forward implemented and computationally efficient approach of selecting a predetermined number of unused codes is used to perform weighted linear combination selectively with each of the input spread signals in a multiple access communication system. If desired, the predetermined number of unused codes is always the same in each implementation. Alternatively, the predetermined number of unused codes is selected from within a reordered code matrix using knowledge that is shared between the two ends of a communication system, such as between the CMs and a CMTS. While the context of an S-CDMA communication system having CMs and a CMTS is used, the solution is generally applicable to any communication system that seeks to cancel narrowband interference. Several embodiments are also described that show the generic applicability of the solution across a wide variety of systems.
