    Abstract: A block interleaver (212) suitable for communication over fading channels with convolutionally coded signals as input is disclosed. The block interleaver (212) implements multiple interleaving distances which are matched to the particular convolutional code to provide better performance than conventional block interleavers.

    Abstract: In a wireless communication system, a scheduler (100) determines (306) a first set of modulation and coding schemes (MCSs), each of which produces a maximum data rate for a first user, in accordance with available resource constraints (304) of the wireless communication system. The scheduler then forms, for each MCS of the first set, a second set of MCSs that produces the maximum data rate for a second user in accordance with a first residual resource (314) that remains when applying that MCS to the first user, thereby producing (316) a group of second sets of MCSs. After producing the group of second sets, the scheduler selects (324), from the first set and for the first user, a first optimal MCS corresponding to one of the group of second sets that allows a highest maximum data rate for the second user.

    Abstract: A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.

    Abstract: Power control bit generation for forward link power control in a spread spectrum communication system is accomplished through modification of a set point threshold. Modification of the set point reduces the number of squaring and division mathematical operations, thus more efficiently utilizing limited system resources in a mobile receiver used in forward link power control.

    Abstract: A decoding method and apparatus performs a forward recursion process on recursive convolutionally generated symbols and performs backward recursion on the symbols wherein a next state for the backward recursion process is based on linearly combining both a plurality of bits defining a current state of a backward recursion process and a hypothesized information bit. In one embodiment, a backward state determinator (200) combines all binary bits in a current state backward recursion register (202) to generate a most significant bit (MSB) (210) of a next state backward recursion register (204). To obtain remaining bits of the next state backward recursion register (204), bits (207a - 207n) in the current state backward recursion register (202) are shifted. The shifted bits then serve as the least significant bits (208a - 208n) in the next state backward recursion register (204). Accordingly, a suitable linear combination and bit shifting approach is used to determine the content of a next state backward recursion register (204).
