    • A technique for using energy received by subscriber units over multiple orthogonal channels within a spread spectrum communication system to acquire signal timing by controlling signal amplitude integration intervals used in detecting such timing. Received signals (10, 14, 18) are despread (40, 60) and respective amplitues coherently integrated (42, 44, 46, 62) over periods that are divisible by factors of two into the length of Walsh functions used to generate orthogonal signal channels. Non-coherent combinations of the results of this integration are subsequently formed (68) over periods that commence and terminate on Walsh function boundaries, and used to determine when a correct time offset has been selected for despreading signals. Additional advantages are realized by assigning signals that consistently provide a higher energy content such as paging, synchronization, and most frequently assigned traffic channels to specific orthogonal channels within the communication system. In exemplary embodiments, Walsh functions of length 128 are used as channelizing codes and a pilot signal is assigned to channel 0. This results in traffic channels or paging and synchronization functions being assigned to channel (64) when the integration periods are (64) chips long, and to channels (32, 64 and 96) when the periods are (32) chips long. In this manner, additional energy is available during the integration process for use in determining when correct signal acquisition timing offsets have been selected, without the use of additional hardware.
    • 一种用于在扩展频谱通信系统内的多个正交信道上使用由用户单元接收的能量的技术,用于通过控制用于检测这种定时的信号幅度积分间隔来获取信号定时。 接收信号(10,14,18)被解扩(40,60)和相应的放大器相干地整合(42,44,46,62),这些周期可被二进制因素分解成用于产生正交信号的沃尔什函数的长度 通道。 随后在Walsh函数边界开始和终止的时段内形成(68)该积分结果的非相干组合,并用于确定何时为解扩信号选择了正确的时间偏移。 额外的优点是通过分配一致地向通信系统内的特定正交信道提供诸如寻呼,同步和最频繁分配的业务信道的更高能量内容的信号来实现。 在示例性实施例中,使用长度为128的沃尔什函数作为信道化码,并将导频信号分配给信道0.这导致当积分周期为(64)码片时,业务信道或寻呼和同步功能被分配给信道(64) 长(32),芯片长(32),(32,64和96)。 以这种方式,在集成过程期间可以使用额外的能量来用于确定何时选择正确的信号采集定时偏移,而不使用额外的硬件。

    • The hands-free, two way communication radio includes a multiple channel transmitter/receiver having one of the channels designated a primary communication channel. The transmitter/receiver is also operable in a scan mode to scan multiple channels for communication signals. The radio also includes an interface operatively connected to the multiple channel transmitter/receiver and a hands-free microphone operatively connected to the transmitter/receiver through the interface. A foot pedal actuator is provided for keying the hands-free microphone to allow transmission of a message over the multiple channel transmitter/receiver. Further, the radio includes a switching mechanism operative in response to actuation of the foot pedal for providing a control signal to the multiple channel transmitter/receiver. This control signal results in the multiple channel transmitter/receiver switching to the primary communication channel for transmission of the message. The invention also includes the combination of the interface, hands-free microphone and foot pedal actuator and switching system for retrofit conversion of a standard radio to hands-free operation.
