摘要： This invention provides a method for bit detection of the GFSK signals at the receiver end. The bit detection is done digitally after the carrier is removed. It employs differential detection incorporated with decision feedback, which uses previous one (so-called on-bit differential detection), or two (so-called two-bit differential detection) bits as correcting information. In addition, synchronization for bit timing and frequency offset resulted from clocks between the transmitter and receiver are also performed with or without preamble as prior information. If preamble is available, the bit timing and frequency-offset bias are estimated from the preamble, which is the case of this present invention. If preamble is not available, this information is estimated directly from the unknown received signals. Once the information about the bit timing and frequency offset is obtained, it is used for the following bit detection.

摘要： Two multi-rate transmission schemes, multi-code (MC) and variable-spreading-length (VSL) code, for realizing multimedia communications on three types of OFDM-CDMA systems are proposed. These systems can be integrated into a programmable structure such that the operation can be controlled and adjusted by system parameters and thus the transceiver can be used in different systems without changing the fundamental hardware and software architecture, which serves the trend of software-radio for future application. A transceiver architecture of multi-rate OFDM-CDMA systems is illustrated and showed its programmability such that the general system can operate under different scenarios with a common hardware structure and reconfigure by software implementation.

摘要： A method to provide improved medium access control (MAC) protocol for a wireless local area network (LAN) comprising the steps of: (a) pre-arranging a polling cycle to be broadcast from the base station into a sequence of broadcast groups, (b) assigning each active mobile node to a randomly chosen broadcast group, (c) performing a group randomly addressed polling for each of the broadcast groups, and (d) assigning uncollided mobile nodes to their original randomly chosen broadcast group address. The uncollided mobile nodes will also be given the privilege of keeping their random numbers as fixed random numbers, until they collide with other mobile node(s) in subsequent polling cycle(s). All the collided mobile nodes, all newly active mobiles, and all newly joined mobile nodes are subject to a new polling cycle. The method has shown to provide excellent throughput (better than 0.90), stable convergence, and excellent delay behavior.

摘要： A randomly addressed polling (RAP) method for wireless networks is proposed to meet the requirements for wireless LANs which remain open to the research community. The RAP method has the following steps: When a base station is ready to conduct an up-link communication, it broadcasts a ready message to all users under its coverage; each user whenever has a packet to transmit generates a random number; all random numbers are simultaneously transmitted to the base station in response to the ready message; base station collects the random numbers, and polls the active users according to the collected random numbers; and when the base station successfully/unsuccessfully receives the packet from the user, it sends a positive/negative acknowledgment to the user.
