Embodiment 1

[0035] like figure 1 Shown is a schematic structural diagram of the integrated intercom chip provided by this embodiment, the integrated intercom chip 10 includes: an audio codec unit 11, a micro control unit 12, a baseband processing unit 13 and a radio frequency transceiver unit 14, and the audio codec unit 11 , the micro control unit 12, the baseband processing unit 13 and the radio frequency transceiver unit 14 are integrated by a system-on-chip process, and the audio codec unit 11, the baseband processing unit 13 and the radio frequency transceiver unit 14 are electrically connected with the micro control unit 12 respectively; the micro control unit 12 is used to control at least one unit on the receiving path to detect the receiving performance parameters of the signal received in the receiving time slot; the micro-control unit 12 is also used to perform mapping according to the receiving performance parameters and the preset receiving performance parameters and sending p...

Embodiment 2

[0052] This embodiment provides an integrated intercom terminal, figure 2 Shows a schematic structural diagram of the integrated intercom terminal, the integrated intercom terminal 20 includes the integrated intercom chip 10 as described in the first embodiment above and an audio input unit 21 electrically connected to the integrated intercom chip 10, audio output unit 22 and communication antenna 23 . The integrated intercom terminal uses the aforementioned integrated intercom chip to realize the intercom function. It should be noted that the integrated intercom terminal can be an analog integrated intercom terminal or a digital integrated intercom terminal. The communication mechanism it supports And systems include but are not limited to one or any combination of the following: digital walkie-talkie system (dPMR, DMR, PDT), global system for mobile communication GSM, code division multiple access CDMA, wideband code division multiple access WCDMA, time division synchronous...

Embodiment 3

[0054] In order to solve the defect that the intercom equipment in the prior art cannot take effective countermeasures in real time according to the channel quality when the channel quality changes, resulting in the defect that the quality of voice communication cannot be guaranteed, this embodiment provides a signal transmission processing The method is applied to an integrated intercom chip integrated with an audio codec unit, a micro control unit, a baseband processing unit and a radio frequency transceiver unit through a system-level chip process, such as image 3 Shown is the basic flow chart of the signal transmission processing method provided in this embodiment, which specifically includes the following steps:

[0055] S301. At least one unit on a receiving path detects a receiving performance parameter of a signal received in a receiving time slot.

[0056] Optionally, the receiving performance parameter in this embodiment is obtained based on at least one of received...

Abstract

The invention provides an integrated talkback chip, an integrated talkback terminal and a signal transmission processing method. The integrated talkback chip includes an audio coding and decoding unit, a micro control unit, a baseband processing unit and a radio frequency transmitting-receiving unit; the audio coding and decoding unit, the micro control unit, the baseband processing unit and the radio frequency transmitting-receiving unit are integrated through a system-level chip process; the audio coding and decoding unit, the baseband processing unit and the radio frequency transmitting-receiving unit are electrically connected with the micro control unit; the unit on a receiving path is controlled to perform performance evaluation on signals received at a receiving time slot; the uniton a transmission path is controlled to process signals to be transmitted at a transmission time slot according to a receiving performance parameter obtained through the evaluation; and therefore, a corresponding processing strategy is quickly adopted to process the signals to be transmitted at the transmission time slot in real time according to the signal evaluation data of the receiving time slot, the adaptive processing of the signals to be transmitted is realized, and the quality of voice communication on an uplink can be effectively ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an integrated intercom chip, an integrated intercom terminal and a signal sending and processing method. Background technique [0002] As one of the important equipment of professional mobile communication system, intercom equipment is widely used in public utilities, schools, hospitals, hotels, animal husbandry and other industries. In narrowband wireless communication, the signal is transmitted in a complex environment, and the channel quality is constantly changing due to factors such as terrain and weather, which greatly affects the communication capability of the intercom device. To take effective countermeasures in real time, the voice communication quality of the intercom equipment cannot be guaranteed when it is working, and it cannot well meet the needs of users. Contents of the invention [0003] The present invention provides an integrated intercom chip, an i...
