International Classification:

H04B 138

US Classification:

455561, 4555501, 455500

Abstract:

A telecommunication base station transceiver subsystem that can be easily configured to provide single or multi-carrier frequency service. The base station is divided into a main unit and a radio unit such that the radio unit is positioned proximate to the antennas and the main unit is remotely located from the radio unit. A single base station transceiver can provide service via multiple wireless protocols, such as CDMA, TDMA, GSM or Analog. The base station transceiver. can also operate on various transmit/receive frequencies as well as variable transmit power settings. Furthermore, the base station transceiver can be reprogrammed, reconfigured and/or statused by a network operations center.

Abstract:

A processing system (210) subdivides (302) a voice message into a plurality of portions, and estimates (304) a plurality of preferred pitch periods corresponding to the plurality of portions. The processing system calculates (314) a plurality of segment sizes corresponding to the plurality of preferred pitch periods, and compresses (316) each of the plurality of portions by utilizing a corresponding one of the plurality of segment sizes in a speech compression algorithm, thereby generating a compressed message. The processing system determines (326) from the plurality of segment sizes a preferred segment size for decompressing the compressed message; and sends (328) the preferred segment size, along with the compressed message, to a receiver (122) for use in decompressing the compressed message in a speech decompression algorithm.
