【简　介】:This thesis studies a new method of combining Turbo Codes with various modula-tion techniques to take advantage of inherent trade-o®s between BER performance,code rate, spectral e±ciency and decoder complexity. Our new method, which we call Symbol-Based Turbo Codes, parses the parallel data streams of the Turbo Code encoder into n-bit symbols and maps each symbol to a point in a 2n-ary signal set.In the case of Symbol-Based Turbo Codes with BPSK modulation, the BER perfor-mance can be improved while at the same time decreasing the decoder complexity as compared with the traditional Turbo Code.
