    • A wireless communication system (100) and method for providing high speed uplink packet access from user equipment (128, 130) to a base station (114, 116, 118, 120). Each of the user equipment (128, 130) and the base station (114, 116, 118, 120) includes a transmitter (1106, 1206), a receiver (1104, 1204), and a controller (1108, 1208) coupled to the transmitter and the receiver. Data packets are transmitted from the user equipment (128, 130) to the base station (114, 116, 118, 120). Control information, corresponding to the data packets, is transmitted from the base station (114, 116, 118, 120) to the user equipment (128, 130). The control information includes at least a control channel acknowledgement field in an absolute grant channel assigned to the user equipment (128, 130). The controller (1108) of the user equipment (128, 130) is configured to utilize the channelization code(s) in response to handoff and/or entering an active channel state.

    • A demodulator (414) for improving bit error rate performance where alternating bit patterns produce the worst occurrences of bit errors. The demodulator (414) consists of a zero threshold comparator circuit (502), a first threshold detector circuit (508), and a second threshold detector circuit (504). The zero threshold comparator circuit (502) receives a frequency information signal and slices it into a plurality of bits (522). The first threshold detector circuit (508) compares the frequency information signal to a predetermined threshold, which is selected to optimize bit error rate performance. The second detector threshold circuit (504) is used to ensure that an alternating bit pattern has occurred. The demodulator (414) also includes a control device circuit (516) for coupling the plurality of bits (522) from the zero threshold comparator (502) to the output of the control device as a decision output signal (416) when the frequency information signal falls outside of either the first or second detector thresholds (508), (504). If the frequency information signal falls within both thresholds of the detector devices then the decision output signal (416) for the control device (516) is formed by inverting the bit decision from the previous bit interval.
    • 一种用于改善误码率性能的解调器(414),其中交替位模式产生最差出现的位错误。 解调器(414)由零阈值比较器电路(502),第一阈值检测器电路(508)和第二阈值检测器电路(504)组成。 零阈值比较器电路(502)接收频率信息信号并将其分片成多个比特(522)。 第一阈值检测器电路(508)将频率信息信号与预定阈值进行比较,其被选择以优化误码率性能。 第二检测器阈值电路(504)用于确保发生交替位图案。 解调器(414)还包括控制装置电路(516),用于当频率信息(416)作为判定输出信号(416)将多个位(522)从零阈值比较器(502)耦合到控制装置的输出端 信号不在第一或第二检测器阈值(508),(504)之外。 如果频率信息信号落在检测器装置的两个阈值之内,则控制装置(516)的判定输出信号(416)是通过将来自前一位间隔的位决定反相来形成的。
