Abstract: A feedback signal indicative of the average RF power of an APol-DPSK optical signal is used by a PMD compensator to adjust the amount of compensation applied to the optical signal.

Abstract: Embodiments provided include a method for transmitting a packet to a receiver over primary and supplemental channels in a wireless communication network. Indications of a primary code and a set of N supplemental codes assigned to the receiver are communicated over a control channel. When it is determined that a packet should be transmitted over a supplemental channel, a first portion of the packet and a supplemental channel indicator are transmitted over a same single packet transmission time interval on the primary channel and a second portion of the packet is transmitted over the same single packet transmission time interval on the supplemental channel corresponding to the supplemental channel indicator. The supplemental channel uses an assigned specific supplemental code belonging to the set of N supplemental codes assigned to the receiver. When the packet should not be transmitted over a supplemental channel, the packet is transmitted over the primary channel.

Abstract: A method enables the use of a secondary pilot signal and a secondary antenna(s) in the forward link of a CDMA-based cellular network employing a slotted transmission scheme with a time-multiplexed primary pilot signal, with backwards compatibility. The forward link is divided into a number of time slots. For communications with “legacy” mobile stations that expect transmissions from a single, primary antenna (and that expect a single, primary pilot signal), during some of the time slots, only the primary antenna is used for transmissions, including transmitting the primary pilot signal. Neither the secondary pilot channel nor any other signals from the secondary antenna are transmitted. During the remaining time slots: (i) the primary pilot signal is transmitted from the primary antenna, and the secondary pilot signal is transmitted from the secondary antenna, but at different times; and (ii) data meant for the legacy mobile stations is not transmitted.
