摘要： A method and apparatus for mitigating multi-user interference in reception of a code division multiple access (CDMA) signal is described. The CDMA signal has a plurality of spread user symbol streams, each spread by a corresponding one of a plurality of spreading codes. Estimated symbols are iteratively improved by forming a reconstructed signal from the estimated symbols, subtracting the reconstructed signal from the CDMA signal to create a difference signal, and adjusting the estimated symbols based on a combination of the difference signal and the estimated symbols.

摘要： An architecture and a method are provided for decoding codewords for codes such as low density parity check (LDPC) codes. An iterative decoding algorithm such as the Belief Propagation Algorithm (BPA) is employed that attempts to correct errors in an input block of symbols via a structure containing two sets of nodes through node processing and the passing of messages between nodes. Message passing and node processing is performed in a digit-serial manner instead of a bit-parallel manner.

摘要： A method for acquiring signals received from multiple users in a single burst groups signals by power and sequentially processes the signal groups. A received sum of a plurality of user signals received in a burst is stored, and the transmitted symbols for each signal within a first group of the stored signals is estimated. A modified set of signals is then determined that excludes the signals of the first group. From the modified set of signals, the method continues by canceling multiuser interference among signals within a second group, and estimating transmitted symbols for each signal within the second group. The first and second groups includes all signals within a power band that defines the group, and the first band represents a higher power band than the second. Such iterative processing may continue for sequentially lower power bands until all signals are processed. A receiver is also detailed.

The method includes receiving a plurality of user signals in a single transmission burst, suppressing multiuser interference among at least some of the plurality of received signals, and determining a carrier frequency of at least one signal from among the interference suppressed plurality of received signals. Said signals may rotate due to a lack of synchronization while being equalized.

摘要： A receiver (20) for performing timing recovery over at least one complex channel at low or less than zero SNR (signal power to noise power, in dB) has at least one receive element such as an antenna, an analog-to-digital converter 21 (ADC), a fractional interpolation filter 23, a matched filter 24, and a timing correction loop 26. The timing correction loop 26 selects a minimum mean square error from the output of the matched filter 24 to determine a timing signal output to the interpolation filter 23, and provides one-bit weights to the matched filter 24. Preferably, the timing correction loop 26 includes a magnitude detector 26c, a moving average filter 26b, and a timing error detector 26a that outputs an integer m and fractional μ timing factor to the interpolation filter 23. Within a phase correction loop 27 is a maximum likelihood channel estimator 27b and a phase error detector 27a that controls a phase rotator 22 disposed between the ADC 21 and the interpolation filter 23.

摘要： A connecting system for making electrical connections between a multiple conductor cable and a printed circuit board. A plurality of connector pins is mounted in a regularly spaced array on the printed circuit board and projecting above a first surface of the board. No other elements are mounted on the printed circuit board which are dedicated solely to the connecting system. Instead, a plurality of electrical components which are mounted on the circuit board for performing circuit functions, are mechanically positioned to surround the pins to provide an internal periphery of predetermined size, shape, and keyed configuration. The keyed periphery closely matches the outer periphery of a connector body attached to the cable. Thus, the electrical components on the circuit board key the connector body to the circuit board such that misplugging is avoided. The elimination of a board mounted connector body, and the close proximity of the electronic components required to perform their keying function, substantially increases circuit board density.
