N2 - We propose two phase constraining (PC) schemes using quantized feedback for multiple-input single-output (MISO) systems. The PC schemes are generalizations of the quadrature phase constraining (QPC) scheme. One PC scheme cophases channel gains with respect to the first transmit antenna channel gain, and the other PC scheme cophases channel gains by positioning all the channel gains into a fixed sector. We analyze the combined channel gain for both PC schemes, and find that the PC scheme that cophases with respect to the first transmit antenna channel gain provides 1.2 dB power gain over an orthogonal space-time block code (OSTBC) when the number of transmit antennas is four and the number of feedback bits is three.
