Performance of multiple amplitudes differential space-time block coding scheme concatenated with channel coding
By introducing multiple levels quadrature amplitude modulation and matrix transform method,a multiple am-plitudes differential space-time coding（DSTC） scheme was developed.The scheme can avoid the performance loss of conventional DSTC schemes based on PSK modulation in high spectrum efficiency,and i...

| description | By introducing multiple levels quadrature amplitude modulation and matrix transform method,a multiple am-plitudes differential space-time coding（DSTC） scheme was developed.The scheme can avoid the performance loss of conventional DSTC schemes based on PSK modulation in high spectrum efficiency,and it can be applied to non-square code matrix.Compared with conventional PSK based single amplitude DSTC schemes,the developed scheme has higher spectrum efficiency by carrying information not only on phases but also on amplitudes.Moreover,it has linear decoding complexity,and higher code rate.Also,the performance of our DSTC scheme concatenated with channel codes was given.The simulations results show that our scheme has lower BER when compared with single amplitude DSTC schemes.And multiple amplitudes DSTC concatenated with channel coding also outperform corresponding single amplitude DSTC. |
