Grassmannian Line Packings with Defined Alphabet (QPSK):
The table below presents our results for Grassmannian Line Packings with QPSK Alphabet. These Packings contains codebooks where every codeword has elements from QPSK constellation { 1,-1,i,-i}. They , by definition, are also constant modulus codebooks. These codebooks simplify the mathematical operations at the receiver and also satisfy LTE codebook requirements. They codebooks are free to download (Please see Conditions of Use).
