MATLAB Simulation Program for Ultra-Wideband System Link

This is a MATLAB-based simulation platform for ultra-wideband (UWB) communication links featuring a simple GUI interface. The platform includes modular components such as configurable pulse shaping (half-cosine pulse), modified IEEE 802.15.3a SV channel model, maximum likelihood channel estimation, and Rake receiver implementation. It supports Monte Carlo simulations for bit error rate analysis. The system is extensible with multiple access capabilities and coding modules (Viterbi encoder/decoder and frame synchronization modules were contributed by colleagues). Main entry point: uwbsim.m. Encoding/decoding modules: bin2deci.m, bini2deci.m, deci2bin.m, VITRBI.m. Channel and estimation modules: ch_est.m, channel.m, channelgenerator.m, conv_m.m, sigfold.m, UWB_SV_channel.m, uwb_sv_cnvrt_ct.m, uwb_sv_eval_ct.m, uwb_sv_model_ct.m, uwb_sv_params.m. Rake receiver components: findpeak.m, MRC_combine.m, MRC_Rake.m, n_upsample.m, selectpath.m. Additional utilities: cnv_encd.m, dssignal.m, Eb_halfcos.m, waveshape.m, halfcos_generator.m, metric.m, nxt_stat.m, sim_main.m, spreadgren.m, test_code.m, training_ds.m, uwbsim.m, vit_test.m.
