摘要： A method and apparatus for mitigating error in a received communications signal includes an error mitigator (35) of a communication unit (12) which receives and performs mitigation based on an error indication. In a first embodiment the error indication is a phase or non-used data symbol indicating error in ADPCM data, and mitigation includes changing certain nibble values to different predetermined values. In a second embodiment the error indication may include other parameters, e.g., a CRC frame error indicator, and an error estimator (34) determines a level of corruption in the ADPCM data. The error mitigator (35) applies a predetermined set of replacement values based on the indicated level of corruption and the mitigated data is subsequently decoded in an ADPCM decoder (26).

摘要： A method of interleaving data for transmission is provided wherein first and second interleaving patterns for arranging data symbols in a source data stream into first and second transmitted data streams are selected. Each of said data symbols has at least one bit. The first and second transmitted data streams are transmitted substantially simultaneously on separate transmission channels to at least one receiver. The first and second patterns are used to transmit the data symbols in the source data stream in a different order on the respective transmission channels to maximize recovery of the source data stream when the transmission channels are blocked. The selected interleaving patterns can involve reordering the data symbols throughout the first and second transmitted data streams using different reordering criteria The reordering. criteria can vary on a frame-by-frame basis if the source data stream is time division multiplexed. Complementary data can be sent on respective transmission channels.

摘要： A method for providing two-way calling between first and second handsets (402, 404) using a base station (406) and a paging terminal (412). The method for making the call includes storing a base line phone number for each line within the base station (406). A communication link is established between the first handset (402) and the base station (406) and between the base station (406) and the paging terminal (412). The paging terminal (412) prompts the caller for information to be sent to the second handset and the caller responds by entering a sequence that allows the base station itself to forward the base line phone number and an alias code, representing the identification of the first handset, to the paging terminal (412). The paging terminal (412) then pages the second handset (404) with the base line phone number and the alias code. Any communciations device may return the call by calling the base line phone number and entering the alias code, thus establishing a communications link with the first handset (402).

摘要： A base site circuit (38) for operating in a communication system (10) having a plurality of base sites capable of allocating a communication channel for use by a communication unit (16) in response to a communication channel request from the communication unit. The base site circuit includes a receiver (34) that operates in a low sensitivity mode when there are no communication channel requests received, and that operates in a high sensitivity mode which is activated by a control signal. The base site further includes a transmitter (34) which is activated by the control signal and a control circuit (32) coupled to both the receiver and the transmitter, for controlling the receiver and the transmitter. The control circuit (32) provides the control signal to the transmitter and to the receiver, in response to a communication channel request.

摘要： A nested digital phase lock loop (DPLL) circuit (400) provides center bit sampling for incoming recovered data (406). Included in the nested DPLL circuit (400) are a narrow bandwidth DPLL (402) and a wide bandwidth DPLL (404) which generate first (410) and second (428) recovered clock signals respectively. Initially the first recovered clock signal (410) is used to clock in the recovered data (406) until the narrowband DPLL (402) is stabilized. Once the narrowband DPLL (402) is stabilized, the second recovered clock signal (428) generated from the wideband DPLL (404) is switched in by a multiplexer (424). If for any reason the center bit sampled data becomes corrupted, a RESET occurs in the wideband loop (404) to zero out the phase shift of the second recovered clock signal (428) to match that of the narrow loop. Thus, when a RESET occurs, the wideband loop is tracking at exactly the same clock rate as the narrowband loop.
摘要翻译：嵌套数字锁相环（DPLL）电路（400）为输入的恢复数据（406）提供中心位采样。包含在嵌套DPLL电路（400）中的是窄带宽DPLL（402）和宽带宽DPLL（404），其分别产生第一（410）和第二（428）恢复的时钟信号。最初，第一恢复时钟信号（410）用于在恢复的数据（406）中进行时钟，直到窄带DPLL（402）稳定为止。一旦窄带DPLL（402）稳定，则从宽带DPLL（404）产生的第二恢复时钟信号（428）被多路复用器（424）切换。如果由于任何原因，中心位采样数据被破坏，则在宽带环路（404）中发生复位以将第二恢复时钟信号（428）的相移清零以匹配窄环路的相移。因此，当发生RESET时，宽带环路跟窄带环路完全相同的时钟速率进行跟踪。
