Filed:

May 9, 2000

Appl. No.:

09/567252

Inventors:

Scott David Kurtz - Mount Laurel NJ

Assignee:

Interdigital Technology Corporation - Wilmington DE

International Classification:

H04J 400

US Classification:

370344, 370468, 370478, 370493, 370496, 370526, 379 9309, 455509

Abstract:

Two related voiceband compression techniques are employed in order to enable an RF telecommunications system to accommodate data signals of high speed voiceband modems and FAX machines. A High Speed Codec enables the telecommunications system to pass voiceband modem and FAX transmissions at up to 9. 6 kb/s. An Ultra-High Speed Codec supports voiceband modem and FAX transmissions up to 14. 4 kb/s. The High Speed Codec operates using three 16-phase RF slots or four 8-phase RF slots, and the Ultra-High Speed Codec operates using four 16-phase RF slots. Because these codecs transmit information over several RF slots which can be contiguous, the slots within RF communication channels are dynamically allocated. The Dynamic Timeslot/Bandwidth Allocation feature detects and monitors the data transmission and forms a data channel from the necessary number of slots.

Inventors:

Scott David Kurtz - Mount Laurel NJ

Assignee:

InterDigital Technology Corporation - Wilmington DE

International Classification:

H04L 700

US Classification:

375356, 375211, 455 132, 370274

Abstract:

A wireless digital telephone system containing at least one emulated base station plus one or more subscriber stations, the emulated base station comprising a station similar to the subscriber station but having the capability of initiating a synchronization process whereby it is enabled to assign time slots to the subscriber station within the frame pattern of an amplitude signal by means of monitoring for positive edges in the signal.

Inventors:

Scott David Kurtz - Burlington NJ, US

Assignee:

Adaptive Digital Technologies, Inc. - Conshoken PA

International Classification:

H04M001/00

US Classification:

379386, 379372

Abstract:

A DFT is used to compute the magnitude and phase of the frequencies desired to be detected in a frame of sampled data by performing 2 dot products for each such frequency. The two dot products are calculated using the samples in the frame and an equal number of equally spaced cosine and sine coefficients for each frequency to be detected.
