摘要： 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.

摘要： 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.

摘要： 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).
摘要翻译：解码方法和装置对递归卷积生成的符号执行正向递归处理，并对符号执行反向递归，其中用于反向递归处理的下一状态是基于定义反向递归处理的当前状态的多个比特和假设的信息位。在一个实施例中，后向状态确定器（200）组合当前状态反向递归寄存器（202）中的所有二进制位以产生下一状态向递归寄存器（204）的最高有效位（MSB）（210）。为了获得下一状态反向递归寄存器（204）的剩余位，当前状态反向递归寄存器（202）中的位（207a-207n）被移位。移位的位然后用作下一状态反向递归寄存器（204）中的最低有效位（208a-208n）。因此，使用适当的线性组合和比特移位方法来确定下一状态反向递归寄存器（204）的内容。
