Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a time slot location allocation level, which truly and effectively solves the time slot allocation problem in the MF-TDMA system, and can complete the uniform allocation of the number of time slots in any system, and It can complete the uniform time slot allocation when the number of system time slots is not the nth power of 2; it can effectively reduce the service delay, and the MF-TDMA system uniform time based on the minimum mean square error criterion with better delay and delay jitter performance slot allocation method

Embodiment Construction

[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the content protected by the present invention is not limited to the following description.

[0019] like figure 1 Shown, the MF-TDMA system uniform time slot allocation method based on the minimum mean square error criterion, it comprises the following steps:

[0020] S1: The number of time slots determined according to the system is recorded as N;

[0021] S2: Number each time slot starting from 0, that is, [0, N-1];

[0022] S3: Map the time slot number [0, N-1] according to the time slot allocation scheme searched by the minimum mean square error sum method, for example, for a system with 8 time slots, the mapping scheme is: [0, 3, 6, 1, 4, 7, 2, 5] or rotate it;

[0023] S4: Use the new time slot number after mapping as the time slot for the terminal burst.

[0024] The time slot number mapping method in the step S3 is: respectively...

Abstract

The invention discloses a MF-TDMA system uniform time slot allocation method based on the minimum mean square error criterion, which includes the following steps: S1: determine the number N of time slots according to the system; S2: start from 0 for each time slot number; S3: Map the time slot number [0, N‑1] according to the searched time slot allocation scheme; S4: use the mapped new time slot number as the time slot for the terminal burst. The present invention effectively solves the problem of time slot allocation in the MF-TDMA system at the level of time slot position allocation, can complete the uniform allocation of the number of time slots in any system, and can complete the number of time slots in the system that is not the power of 2 Uniform time slot allocation; it can effectively reduce service delay, and the performance of delay and delay jitter is better.

Description

technical field [0001] The invention relates to an MF-TDMA system uniform time slot allocation method based on the minimum mean square error criterion. Background technique [0002] In a wireless communication system using MF-TDMA technology, all terminals share wireless link resources, and the system allocates certain wireless transmission resources (that is, time slots) for each user to transmit data. The result is expressed in the number of allocated slots per frame. The terminal can only send data in a burst mode on the time slot allocated to it in each MF-TDMA frame. When a data packet arrives at a terminal, it must wait until the beginning of a time slot allocated for the terminal before sending data. Time slot allocation is an important task of the MF-TDMA system, and it is an important factor that affects service delay, delay jitter performance and overall system performance (radio resource utilization, etc.), especially for voice, etc. High real-time business eff...
