A Bandband Processor for Wireless Communications is presented. The invention encompasses several improved Turbo codes method to provide a more practical and simpler method for implementation a Turbo Codes Decoder in ASIC or DSP coding. (1) A plurality of pipelined pipelined Log-MAP decoders are used for iterative decoding of received data. (2) In a pipeline mode, Decoder A decodes data from the De-interleaver RAM memory while the Decoder B decodes data from the De-interleaver RAM memory at the same time. (3) Log-MAP decoders are simpler to implement in ASIC with only Adder circuits, and are low-power consumption. (4) Pipelined Log-MAP decoders method provide high speed data throughput, one output per clock cycle.

A baseband processor is provided having Turbo Codes Decoders with Diversity processing for computing signals from separate antennas. The invention decodes multipath signals that have arrived at the terminal via different routes after being reflected from buildings, trees or hills. The Turbo Codes Decoder with Diversity processing increases the signal to noise ratio (SNR) more than 6 dB which enables the 3 Generation Wireless system to deliver data rates from up to 2 Mbit/s. The invention provides several improved Turbo Codes Decoder methods and devices that provide a more suitable, practical and simpler method for implementation a Turbo Codes Decoder in ASIC or DSP codes. A plurality of parallel Turbo Codes Decoder blocks are provided to compute soft-decoded data RXDa, RXDb from two different receiver path. Several pipelined Log-MAP decoders are used for iterative decoding of received data. A Sliding Window of Block N data is used on the inputted data for pipeline operations.

The invention encompasses several improved Turbo Codes Decoder method and apparatus to provide a more suitable, practical and simpler method for implementation a Turbo Codes Decoder in ASIC or DSP codes. (1) Two pipelined Log-MAP decoders are used for iterative decoding of received data. (2) A Sliding Window of Block N data are used on the input Memory for pipeline operations. (3) The output block N data from the first decoder A are stored in the RAM memory A, and the second decoder B stores output data in the RAM memory B, such that in pipeline mode Decoder A decodes block N data from the RAM memory B while the Decoder B decodes block N data from the RAM memory A at the same clock cycle. (4) Log-MAP decoders are simpler to implement in ASIC and DSP codes with, only Adder circuits, and are low-power consumption. (5) Pipelined Log-MAP decoders architecture provides high speed data throughput, one output per clock cycle.

The present invention encompasses several improved methods and architecture of an UMTS modem for delivering optimum high-speed broadband information, commerce and multimedia entertainment services to mobile users via fixed, wireless and satellite IP networks. The present invention utilizes Turbo Codes baseband processor for optimum performance in decoding received data in limited power and noisy environments. The present invention provides a method for dividing the high-speed bit-stream into multiple slow-speed sub bit-streams, and also dividing the UMTS broadband channel into multiple sub-channels for transmitting each sub bit-stream in the assigned adjacent sub-channels, and the uses of the Orthogonal Frequency Division Multiplexing method implemented by N-point complex FFT/iFFT processor in which it effectively divides the broadband high-speed channel into multiple slow-speed N sub-channels where multiple adjacent channels transmit their carriers' frequency which are orthogonal to each other. Also, when M is smaller than N, channels hopping can be done by reassigning a bit-stream to another sub-channel slot.
