[Other] ADAPTIVE-MRIMM-ALGORITHM-FOR

Description: In this paper, tracking a manoeuvring target with a phased array is considered. A new algorithm, called the Adaptive Multi Rate Interacting Multiple models (AMRIMM) algorithm is presented. The AMRIMM algorithm adds to the MRIMM the ability to select the next update time adaptively, according to the motion of target. In this algorithm, the manoeuvring model operates at full rate, while the non manoeuvring model operates at half rate. A discrete wavelet transform is used to solve the problem raised by the difference in the update rate between the two models. The performances of the AMRIMM algorithm are compared to that of the MRIMM algorithm and the IMM algorithm that use a fixed update time, via Monte Carlo simulations.

[Voice Compress] AMR_CodeDecode

Description: C代码实现的AMR语音编解码。AMR多速率编解码技术相比原有的GSM语音编码器采用固定的编码速率，AMR语音编码器则可根据无线信道和传输状况来自适应地选择一种最佳信道模式（全速率或半速率）和信源编码模式（以比特率来区分）进行编码传输。-C code to achieve AMR voice codec. AMR multi rate coding and decoding technology of GSM speech coder is compared to the original fixed code rate, AMR speech coder can be based on the wireless channel and the transmission state to adaptively an optimal channel mode (full rate or half rate) and source coding mode (to distinguish between the transmission with a bit rate).

[Program doc] viterbi_deco

Description: Viterbi decoding of convolutional code with half rate & four state. It can done by two matrics . that is branch metrics and path metrics. Branch metrics is hamming distance between the parity bits and received bits. If branch metrics is zero then no error. Otherwise bit error occurred.path metrics is the hamming distance of path initial state to current state.the path with smallest distance result in less number of bit errors.-Viterbi decoding of convolutional code with half rate & four state.
