Embedded forward reference and control
First Claim
1. In a wireless microcell distribution system in which a channel is dedicated for carrying telephony signals amongst CATV signals carried on other channels, a method of eliminating roll off and cable tilt which are the result of providing reference and control signals below the forward CATV band, comprising:
- locating the forward reference and control signals within the channel dedicated for carrying telephony signals, wherein the forward reference and control signals sandwich the telephony signals in the dedicated telephony channel.

Abstract
In a wireless microcell distribution system, a method is provided for embedding reference and control signals within the channel utilized for carrying the telephony signals, thereby eliminating roll off and cable tilt issues which are the result of providing the reference and control signals below the forward CATV band. The elimination of the signals below the forward CATV band also eliminates additional cable spectrum and installation difficulties which are the result of cable tilt in which frequency dependent amplitudes require compensation through the utilization of equalization for each cable microcell integrator.

2. Apparatus used in a wireless microcell distribution network for developing forward reference and control signals to be used in the operation of a cable microcell integrator comprising;
-
means at said cable microcell integrator for detecting signals in a channel dedicated for telephony said signals including telephony signals and forward reference and control signals transmitted within said dedicated channel, said forward reference and control signals sandwiching the telephony signals;
means for filtering out said forward reference and control signals;
means for down converting the signaling in said dedicated channel; and
,whereby the order of said forward reference and control signals is reversed.
