Abstract:

A method () and a mobile station () for reporting multi-path signals based on minimum separation are described herein. The mobile station () may include a list with a first energy/position pair corresponding to the energy parameter and the position parameter associated with a first multi-path signal of a synchronization code. The mobile station () may generate a second energy/position pair corresponding to the energy parameter and the position parameter of a second multi-path signal. The mobile station () may detect the position parameter of the second energy/position pair being within a minimum separation associated with the position parameter of the first energy/position pair. The mobile station () may also detect the energy parameter of the second energy/position pair being greater than the energy parameter of the first energy/position pair. Accordingly, the mobile station () may replace the first energy/position pair on the list with the second energy/position pair.

US Classification:

370311, 370335, 370441

Abstract:

An apparatus for acquiring a pseudo-random (PN) sequence timing for a code division multiple access (CDMA) radiotelephone. A buffer stores samples of representations of at least one pilot signal. A correlator coupled to the buffer is operable to correlate at least a portion of the samples with a PN sequence at each of a plurality of different PN offsets to produce corresponding correlation energies. A controller coupled to the correlator interrupts the correlator as soon as the PN sequence at a particular PN offset produces a correlation energy at least equal to an energy threshold.

Appl. No.:

11/779499

Inventors:

Christopher J. Becker - Palatine IL, US

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

G11C 29/00

US Classification:

714763, 714762

Abstract:

A decoding circuit includes a mixed modulation memory access circuit responsive to burst rejection information. The mixed modulation memory access circuit selectively accesses burst memory locations containing a valid burst of coded bits. The mixed modulation memory access circuit selectively avoids accessing burst memory locations containing a rejected burst of coded bits based on the burst rejection information. In one example, the mixed modulation memory access circuit accesses the valid burst when the burst rejection information indicates that the memory location contains valid bursts. In one example, the mixed modulation memory access circuit generates zero confidence information when the burst rejection information indicates that the memory location contains rejected bursts.

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

H03M 13/03

US Classification:

Abstract:

Methods and corresponding systems in a Viterbi decoder include selecting an input symbol in an input block, wherein the input block has a plurality of input symbols, wherein each input symbol has a Boolean value, a quality value, and an associated stage, and wherein the selected symbol is selected based upon the quality value of the selected symbol relative to a quality value of other input symbols in the input block. Thereafter, the Boolean value of the selected symbol is complemented to produce a complemented symbol. The complemented symbol is substituted for the selected symbol to produce an alternate input block. A Viterbi algorithm is executed using the alternate input block to produce an alternate decoded bit sequence, which is then checked for errors using an error check. The alternate decoded bit sequence is output in response to the alternate decoded bit sequence passing the error check.

International Classification:

G06F 11/00

US Classification:

714796, 714792, 714794, 714795

Abstract:

Methods and corresponding systems in a Viterbi decoder include computing a maximum likelihood (ML) path in a Viterbi trellis in response to executing a first Viterbi algorithm. Thereafter, one or more merge points are selected on the ML path in a second Viterbi algorithm, wherein the merge points each have a path metric difference, which is a difference between an ML path metric at the merge point and a non-surviving path metric at the merge point. Merge points are selected based upon relative path metric differences associated with nodes on the ML path. Next, alternate paths in the Viterbi trellis are computed based on the ML path with alternate paths substituted at corresponding merge points. A passing decoded bit sequence is output in response to passing an error check, wherein the passing decoded bit sequence is associated with one of the one or more alternate paths.
