Abstract
Spatial modulation (SM) is a special type of Massive MIMO technology, which utilizes the index of transmit antenna to carry some information bits. Recently, a novel spatial modulation called ABPM appears, which uses the index of antenna beam pattern to carry some information bits. When the receivers are located at the cross points of all beam patterns, ABPM is better than traditional spatial modulation in term of bit error rate (BER). However, the probability that receivers located at the position above is low. Thus ABPM can not be widely used in application. In order to solve this problem, this paper proposes a new method of beam pattern modulation based on cosine function pattern (M-CBPM), the scheme uses the Woodword-Lawson algorithm to calculate the weighted vectors and is more suitable for mobile communication scenarios. The results of theory analysis and simulation show that M-CBPM is better than traditional spatial modulation in term of BER and transmission rate.
