A block polyphase filter is constructed of a set of filter blocks having different filter functions, and being arranged for parallel processing of portions of an input sequence of signals. Signals of the input sequence are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. The filter blocks are arranged in groups, wherein output signals of the blocks in any one group are summed to produce an output signal of the filtered group. Output signals of all of the filter groups are multiplexed to provide an output signal sequence wherein the repetition frequency of the signals may be higher, lower, or equal to the repetition frequency of the input signal sequence depending upon the ratio of the number of filter groups to the number of filter blocks in the set of filter blocks.

A demodulator, suitable for use in a communication system and in a modem, has a block polyphase circuit with circuit blocks for different signal processing functions, particularly filtering, delay, and frequency conversion. The circuit blocks are arranged for parallel processing of different portions of an input sequence of signals. Signals of the input sequence to be filtered are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. Signals outputted by groups of the circuit blocks are summed to produce an output signal of the group. Output signals of all of the groups are multiplexed to provide an output signal sequence such that the repetition frequency of the outputted signals may be higher, lower, or equal to that of the input signal sequence. This enables use of programmable circuitry operative at reduced clock rates.

A method and system for using power and timing estimates to acquire frame acquisition of a reverse CDMA carrier signal. The method includes providing at least one remote transceiver device acquiring a forward CDMA carrier signal, and the one remote transceiver device transmitting a reverse CDMA carrier signal modified to include a frequency associated with the forward CDMA carrier signal. A transceiver base station, in response to determining if the reverse CDMA carrier signal exceeds a reverse CDMA carrier signal threshold (RCCST), uses the frequency embedded in the modified reverse CDMA carrier signal to acquire phase of the reverse CDMA carrier signal. Achieving acquisition the transceiver base station signals a mode change to the remote transceiver. Otherwise, the transceiver base station signals the remote transceiver device to slip the reverse CDMA carrier signal a predetermined number of chips; and/or transmit the reverse CDMA carrier signal at a second power level.

A header conduit assembly for a sediment collecting apparatus includes a tubular member having a plurality of mutually spaced (suction) orifices disposed in a linear array extending parallel to an axis of the tubular member. The conduit assembly further includes at least one elongate deflector member mounted to the tubular member in effective proximity to at least some of the orifices to guide sediment toward the orifices during a sediment evacuation process. Preferably, the deflector member extends parallel to the axis of the tubular member. Inasmuch as the tubular conduit member extends perpendicularly to a direction of movement of the conduit assembly on the floor of a clarification basin or tank, the deflector is oriented orthogonally to the path of the conduit assembly.

A method and system is disclosed for demodulating multiple waveforms, with different modulation formats, in the same hardware by providing a software-configurable demodulator that configures itself in response to varying input waveform types. The system reconfigures its logic to accommodate the format of the signals being received and further allows for reconfiguration of demodulator functional block interfaces to remove downtime during multiple waveform processing.
