JP-CoMP Precoding Algorithm in LTE-A System
Zhao Yin · Wireless Communication Technology · 2014
In the LTE- A system,the common precoding algorithm can not eliminate the interference between the inter user interference and its antenna while considering the influence of the system noise,I put forward two kinds of optimization algorithms: one is the BD algorithm combined with the MMSE algorithm; the second is the use of ZF algorithm based on SLNR algorithm. These two kinds of optimization algorithms is a kind of scheme considering the noise influence in the foundation to eliminate all interference,simulation results show that,these two algorithms can effectively reduce the bit error rate of the system,provides the system performance.
