Sae Young Chung, M Vedat Eyuboglu, Yong Hoon Kang, Dae Young Kim, Jin Hwa Ku, Seung Hee Lee, Michael D Pollman: Capacity enhancement schemes for forward and reverse links of distributed cellular base stations. Airvana, Solid Technologies, Fish & Richardson P C, April 3, 2007: US07200391 (299 worldwide citation)

Capacity enhancement schemes are described for forward and reverse links of distributed cellular base stations consisting of a central unit and one or more remote units. In general, in one aspect, reverse link capacity is shared among remote units. The capacity sharing can be determined dynamically. ...

Sae Young Chung: Modulation for broadcasting from multiple transmitters. Airvana, Fish & Richardson P C, April 7, 2009: US07515643 (20 worldwide citation)

In a cellular network, randomness is introduced into a transmitted signal at each transmitter, and the resulting received signal, which is the sum of all received signals, fluctuates more in time than a signal transmitted without the introduced randomness. While the introduction of randomness can di ...
