Method for uniformly allocating time slots of MF-TDMA (Multi-Frequency Time Division Multiple Access) system based on minimum mean square error rule

Abstract

The invention discloses a method for uniformly allocating time slots of an MF-TDMA (Multi-Frequency Time Division Multiple Access) system based on a minimum mean square error rule. The method comprises the following steps: S1, determining the number N of the time slots according to the system; S2, numbering all the time slots from the beginning of 0; S3, mapping time slot numbers [0, N-1] according to a searched time slot allocation scheme; S4, taking mapped new time slot numbers as emergent time slots of a terminal. According to the method disclosed by the invention, levels are allocated at the positions of the time slots, so the allocation of the time slots in the MF-TDMA system is really and effectively realized, uniform allocation of the number of the time slots in any system can be finished, and the uniform allocation of the time slots when the number of the time slots in the system is nth power of an integer except 2 can be finished; in addition, service delay can be effectively reduced, and better time delay and time delay jitter performances are obtained.

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...

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
