New construction of enhanced cross Z-complementary set for generalized spatial modulation
In order to expand the existence space of enhanced cross Z-complementary set(E-CZCS),based on the ex-tended generalized Boolean function(EGBF),the direct construction method of enhanced cross Z-complementary sets was proposed.The constructed q-ary E-CZCS had flexible and variable size,and their length was no longer limited to the traditional power of two.At the same time,the obtained enhanced cross Z-complementary sets was used as the training sequence of the generalized spatial modulation(GSM)system for channel estimation.The simulation results show that the enhanced cross Z-complementary sets can achieve optimal channel estimation.This presumably provides greater flex-ibility in the selection of training sequences in generalized spatial modulation systems.
